Well, I was trying to define Labels from another list that contain hours but no sucess.
def loop_label():
for item in Acd_horario:
Acd_horario[item] = Label(framerajada, text=[Acd_horario[item]],
font=font_acd, bg=bg_acd, fg=fg_acd, bd=bd_acd,
relief=relief_acd)
loop_label()
I tried like above, but no sucess. The other list I`m using is from another class, with gets the hour of another list of objects from the class itself:
Acd_lista = [Acd_0715, Acd_0745, Acd_0815, Acd_0845, Acd_0915, Acd_0945,
Acd_1015, Acd_1045, Acd_1115, Acd_1145,
Acd_1215, Acd_1245, Acd_1315, Acd_1345, Acd_1415, Acd_1445,
Acd_1515, Acd_1545, Acd_1615, Acd_1645,
Acd_1715, Acd_1745, Acd_1815, Acd_1845, Acd_1915, Acd_1945,
Acd_2015]
Acd_horario = [i.horario for i in Acd_lista]
Maybe is my logic that isn't right. Anyone has any idea on this?
The error I receive is: TypeError list indices must be integers or slices, not str

I am trying to build a simple random item generator for a game I am working on.
So far I am stuck trying to figure out how to store and access all of the data. I went with pandas using .csv files to store the data sets.
I want to add weighted probabilities to what items are generated so I tried to read the csv files and compile each list into a new set.
I got the program to pick a random set but got stuck when trying to pull a random row from that set.
I am getting an error when I use .sample() to pull the item row which makes me think I don't understand how pandas works. I think I need to be creating new lists so I can later index and access the various statistics of the items once one is selected.
Once I pull the item I was intending on adding effects that would change the damage and armor and such displayed. So I was thinking of having the new item be its own list then use damage = item[2] + 3 or whatever I need
error is: AttributeError: 'list' object has no attribute 'sample'
Can anyone help with this problem? Maybe there is a better way to set up the data?
here is my code so far:
import pandas as pd
import random
df = [pd.read_csv('weapons.csv'), pd.read_csv('armor.csv'), pd.read_csv('aether_infused.csv')]
def get_item():
item_class = [random.choices(df, weights=(45,40,15), k=1)] #this part seemed to work. When I printed item_class it printed one of the entire lists at the correct odds
item = item_class.sample()
print (item) #to see if the program is working
get_item()
I think you are getting slightly confused with lists vs list elements. This should work. I stubbed your dfs with simple ones
import pandas as pd
import random
# Actual data. Comment it out if you do not have the csv files
df = [pd.read_csv('weapons.csv'), pd.read_csv('armor.csv'), pd.read_csv('aether_infused.csv')]
# My stubs -- uncomment and use this instead of the line above if you want to run this specific example
# df = [pd.DataFrame({'weapons' : ['w1','w2']}), pd.DataFrame({'armor' : ['a1','a2', 'a3']}), pd.DataFrame({'aether' : ['e1','e2', 'e3', 'e4']})]
def get_item():
# I removed [] from the line below -- choices() already returns a list of length 1
item_class = random.choices(df, weights=(45,40,15), k=1)
# I added [0] to choose the first element of item_class which is a list of length 1 from the line above
item = item_class[0].sample()
print (item) #to see if the program is working
get_item()
prints random rows from random dataframes that I setup such as
weapons
1 w2
I have a list like string which I want to convert to a list, but so far I'm unlucky. The string is like follows:
my_string="[749385,435,'20/07/11 05:32','34035',1298,tmp_host_name,'312642',6577,tmp_guest_name,'-0.5,-1.0','2.5,3.0','9.5 ',tmp_league_name,'2' ,'0','0','0','4',' 2','0','1','0.0,-0.5','4.5','1.0',1]"
My problems are:
I can't use eval because some of the items in the list to be are not strings, so it gives me
eval(my_string)
>NameError: name 'tmp_host_name' is not defined
I can't use ast.literal_eval because again, it gives an error
ast.literal_eval(my_string)
>ValueError: malformed node or string: <_ast.Name object at 0x0000017E7DA9E488>
and I can't do it with strip and split because some of the items are like '2.5,3.0' and this is splitted as well, something I don't want
my_string.strip('][').split(',')
['749385','435',"'20/07/11 05:32'", "'34035'",'1298','tmp_host_name',"'312642'",'6577','tmp_guest_name',"'-0.5","-1.0'","'2.5","3.0'","'9.5','tmp_league_name', "'2' ","'0'","'0'","'0'","'4'","' 2'","'0'","'1'","'0.0","-0.5'","'4.5'","'1.0'",'1']
One possible route is to use my last approach and verify that every element has 2 ' characters, and if not, merge it with the following element, but I'm looking for something a little more pythonic.
newlist=list()
for el in k:
if el.startswith("'") and el.endswith("'"):newlist.append(el)
elif el.startswith("'"):
compound=el
elif el.endswith("'"):
compound+=el
newlist.append(compound)
else:newlist.append(el)
Problem is, if I do this, the resulting list loses its order and becomes useless
Thanks!
I have a list of a list that goes like this:
Main_List: [ ['1.2','3.5'],[ ['5.8','8.3'] ]
I am trying to convert one of the sublists into floats, here is what i did:
Main_List[1] = [float(i) for i in Main_List[1]]
but i keep getting an error "ValueError: could not convert string to float: ."
I have tried several other methods but for some reason it keeps complaining about the dot. The lists i am trying to convert have been extracted from a csv file if that makes a difference, but i did print them and they look fine.
What am i doing wrong?
I was able to figure it out, what i had to do is create another list and set it equal to the first sublist then turn all its elements to floats.
for example
Sublist_1 = []
Sublist_1 = MainList[0]
Sublist_1 = map(float, Sublist_1)
I have a List of Lists that looks like this (Python3):
myLOL = ["['1466279297', '703.0']", "['1466279287', '702.0']", "['1466279278', '702.0']", "['1466279268', '706.0']", "['1466279258', '713.0']"]
I'm trying to use a list comprehension to convert the first item of each inner list to an int and the second item to a float so that I end up with this:
newLOL = [[1466279297, 703.0], [1466279287, 702.0], [1466279278, 702.0], [1466279268, 706.0], [1466279258, 713.0]]
I'm learning list comprehensions, can somebody please help me with this syntax?
Thank you!
[edit - to explain why I asked this question]
This question is a means to an end - the syntax requested is needed for testing. I'm collecting sensor data on a ZigBee network, and I'm using an Arduino to format the sensor messages in JSON. These messages are published to an MQTT broker (Mosquitto) running on a Raspberry Pi. A Redis server (also running on the Pi) serves as an in-memory message store. I'm writing a service (python-MQTT client) to parse the JSON and send a LoL (a sample of the data you see in my question) to Redis. Finally, I have a dashboard running on Apache on the Pi. The dashboard utilizes Highcharts to plot the sensor data dynamically (via a web socket connection between the MQTT broker and the browser). Upon loading the page, I pull historical chart data from my Redis LoL to "very quickly" populate the charts on my dashboard (before any realtime data is added dynamically). I realize I can probably format the sensor data the way I want in the Redis store, but that is a problem I haven't worked out yet. Right now, I'm trying to get my historical data to plot correctly in Highcharts. With the data properly formatted, I can get this piece working.
Well, you could use ast.literal_eval:
from ast import literal_eval
myLOL = ["['1466279297', '703.0']", "['1466279287', '702.0']", "['1466279278', '702.0']", "['1466279268', '706.0']", "['1466279258', '713.0']"]
items = [[int(literal_eval(i)[0]), float(literal_eval(i)[1])] for i in myLOL]
Try:
import json
newLOL = [[int(a[0]), float(a[1])] for a in (json.loads(s.replace("'", '"')) for s in myLOL)]
Here I'm considering each element of the list as a JSON, but since it's using ' instead of " for the strings, I have to replace it first (it only works because you said there will be only numbers).
This may work? I wish I was more clever.
newLOL = []
for listObj in myLOL:
listObj = listObj.replace('[', '').replace(']', '').replace("'", '').split(',')
newListObj = [int(listObj[0]), float(listObj[1])]
newLOL.append(newListObj)
Iterates through your current list, peels the string apart into a list by replace un-wanted string chracters and utilizing a split on the comma. Then we take the modified list object and create another new list object with the values being the respective ints and floats. We then append the prepared newListObj to the newLOL list. Considering you want an actual set of lists within your list. Your previously documented input list actually contains strings, which look like lists.
This is a very strange format and the best solution is likely to change the code which generates that.
That being said, you can use ast.literal_eval to safely evaluate the elements of the list as Python tokens:
>>> lit = ast.literal_eval
>>> [[lit(str_val) for str_val in lit(str_list)] for str_list in myLOL]
[[1466279297, 703.0], [1466279287, 702.0], [1466279278, 702.0], [1466279268, 706.0], [1466279258, 713.0]]
We need to do it twice - once to turn the string into a list containing two strings, and then once per resulting string to convert it into a number.
Note that this will succeed even if the strings contain other valid tokens. If you want to validate the format too, you'd want to do something like:
>>> def process_str_list(str_list):
... l = ast.literal_eval(str_list)
... if not isinstance(l, list):
... raise TypeError("Expected list")
... str_int, str_float = l
... return [int(str_int), float(str_float)]
...
>>> [process_str_list(str_list) for str_list in myLOL]
[[1466279297, 703.0], [1466279287, 702.0], [1466279278, 702.0], [1466279268, 706.0], [1466279258, 713.0]]
Your input consists of a list of strings, where each string is the string representation of a list. The first task is to convert the strings back into lists:
import ast
lol2 = map(ast.literal_eval, mylol) # [['1466279297', '703.0'], ...]
Now, you can simply get int and float values from lol2:
newlol = [[int(a[0]), float(a[1])] for a in lol2]
Hi i got a script im working on and its not working out as well as I want it to
This is what I got so far
import bpy
def Key_Frame_Points(): #Gets the key-frame values as an array.
fcurves = bpy.context.active_object.animation_data.action.fcurves
for curve in fcurves:
keyframePoints = fcurves[4].keyframe_points # selects Action channel's axis / attribute
for keyframe in keyframePoints:
print('KEY FRAME POINTS ARE #T ',keyframe.co[0])
KEYFRAME_POINTS_ARRAY = keyframe.co[0]
print(KEYFRAME_POINTS_ARRAY)
Key_Frame_Points()
When I run this its printing out all the keyframes on the selected Objects as I wanted it to. But the problem is that I cant for some reason get the Values its printing into a variable. If you run it and check the the System concole. its acting odd.Like as in its printing out the Values of the Keyframed object.But when I ask it to get those values as an array, its just printing out the last frame.
Here is how it looks like briefly
I think what you want to do is add each keyframe.co[1] to an array which means you want to use KEYFRAME_POINTS_ARRAY.append(keyframe.co[1]) and for that to work you will need to define it as an empty array outside the loop with KEYFRAME_POINTS_ARRAY = []
Note that keyframe.co[0] is the frame that is keyed while keyframe.co[1] is the keyed value at that frame.
Also of note is that you are looping through fcurves but not using each curve.
for curve in fcurves:
keyframePoints = fcurves[4].keyframe_points
By using fcurves[4] here you are reading the same fcurve every time, you probably meant to use keyframePoints = curve.keyframe_points
So I expect you want to have -
import bpy
def Key_Frame_Points(): #Gets the key-frame values as an array.
KEYFRAME_POINTS_ARRAY = []
fcurves = bpy.context.active_object.animation_data.action.fcurves
for curve in fcurves:
keyframePoints = curve.keyframe_points
for keyframe in keyframePoints:
print('KEY FRAME POINTS ARE frame:{} value:{}'.format(keyframe.co[0],keyframe.co[1]))
KEYFRAME_POINTS_ARRAY.append(keyframe.co[1])
return KEYFRAME_POINTS_ARRAY
print(Key_Frame_Points())
You may also be interested to use fcurves.find(data_path) to find a specific curve by it's path.
There is also fcurve.evaluate(frame) that will give you the curve value at any frame not just the keyed values.
