I want to use printing command bellow in many places of my script. But I need to keep replacing "Survived" with some other string.
print(df.Survived.value_counts())
Can I automate the process by formating variable the same way as string? So if I want to replace "Survived" with "different" can I use something like:
var = 'different'
text = 'df.{}.value_counts()'.format(var)
print(text)
unfortunately this prints out "df.different.value_counts()" as as a string, while I need to print the value of df.different.value_counts()
I'm pretty sure alot of IDEs, have this option that is called refactoring, and it allows you to change a similar line of code/string on every line of code to what you need it to be.
I'm aware of VSCode's way of refactoring, is by selecting a part of the code and right click to select the option called change all occurances. This will replace the exact code on every line if it exists.
But if you want to do what you proposed, then eval('df.{}.value_counts()'.format(var)) is an option, but this is very unsecured and dangerous, so a more safer approach would be importing the ast module and using it's literal_eval function which is safer. ast.literal_eval('df.{}.value_counts()'.format(var)).
if ast.literal_eval() doesn't work then try this final solution that works.
def cat():
return 1
text = locals()['df.{}.value_counts'.format(var)]()
Found the way: print(df[var].value_counts())

import docx
doc = docx.Document('CLT.docx')
test = doc.paragraphs[12].runs[2].text
print(test)
doc.save(input('Name of docx file? Make sure to add file extension '))
I've trying to figure out some way to add/edit text to a pre-existing run using python-docx. I've tried test.clear() just to see if I can remove it, but that doesn't seem to work. Additionally, I tried test.add_run('test') and that didn't work either. I know how to add a new run but it will only add it at the end of the paragraph which doesn't help me much. Currently, 'print' will output the text i'd like to alter within the document, "TERMOFINTERNSHIP". Is there something i'm missing?
The text of a run can be edited in its entirety. So to replace "ac" with "abc" you just do something like this:
>>> run.text
"ac"
>>> run.text = "abc"
>>> run.text
"abc"
You cannot simply insert characters at some location; you need to extract the text, edit that str value using Python str methods, and replace it entirely. In a way of thinking, the "editing" is done outside python-docx and you're simply using python-docx for the "before" and "after" versions.
But note that while this is quite true, it's not likely to benefit you much in the general case because runs break at seemingly random locations in a line. So there is no guarantee your search string will occur within a single run. You will need an algorithm that locates all the runs containing any part of the search string, and then allocate your edits accordingly across those runs.
An empty run is valid, so run.text == "" may be a help when there are extra bits in the middle somewhere. Also note that runs can be formatted differently, so if part of your search string is bold and part not, for example, your results may be different than you might want.
I have step where I am have String Array, something like this:
Then Drop-dow patient_breed contains ['Breed1', 'Breed2',.... Breed20']
I need to split this text on two lines. I know that in Gherkin there is expression """. I try something like this:
Then Drop-dow patient_breed contains ['Breed1',
"""
'Breed2',.... Breed20']
"""
It didn't help. Is there any solution?
What do you gain by putting this string in your scenario. IMO all you are doing is making the scenario harder to read!
What do you lose by putting this string in your scenario?
Well first of all you now have to have at least two things the determine the exact contents of the string, the thing in the application that creates it and the hardcoded string in your scenario. So you are repeating yourself.
In addition you've increased the cost of change. Lets say we want our strings to change from 'Breedx' to 'Breed: x'. Now you have to change every scenario that looks at the drop down. This will take much much longer than changing the code.
So what can you do instead?
Change your scenario step so that it becomes Then I should see the patient breeds and delegate the HOW of the presentation of the breeds and even the sort of control that the breeds are presented in to something that is outside of Cucumber e.g. a helper method called by a step definition, or perhaps even something in your codebase.
Try with a datatable approach. You will have to add a DataTable argument in the stepdefinition.
Then Drop-dow patient_breed contains
'Breed1'
'Breed2'
...
...
...
'Breed20']
For a multiline approach try the below. In this you will have to add a String argument to the stepdefinition.
Then Drop-dow patient_breed contains
"""
['Breed1','Breed2',.... Breed20']
"""
I would read the entire string and then split it using Java after it has been passed into the step. In order to keep my step as a one or two liner, I would use a helper method that I implemented myself.
Lets say that there is a function in my Delphi app:
MsgBox
and there is a string which has MsgBox in it.
I know what most of you are going to say is that its possible, but I think it is possible because I opened the compiled exe(compiled using delphi XE2) using a Resource Editor, and that resource editor was built for Delphi. In that, I could see most of the code I wrote, as I wrote it. So since the variables names, function names etc aren't changed during compile, there should a way to execute the functions from a string, but how? Any help will be appreciated.
EDIT:
What I want to do is to create a simple interpreter/scripting engine. And this is how its supposed to work:
There are two files, scr.txt and arg.txt
scr.txt contains:
msg_show
0
arg.txt contains:
"Message"
And now let me explain what that 0 is:
First, scr.txt's first line is function name
second line tells that at which line its arguments are in the arg.txt, i.e 0 tells that "Message" is the argument for msg_show.
I hope my question is now clear.
I want to make a simple scripting engine.
In order to execute arbitrary code stored as text, you need a compiler or an interpreter. Either you need to write one yourself, or embed one that already exists. Realistically, the latter option is your best option. There are a number available but in my view it's hard to look past dwscript.
I think I've already solved my problem! The answer is in this question's first answer.
EDIT:
But with that, as for a workaround of the problem mentioned in first comment, I have a very easy solution.
You don't need to pass all the arguments/parameters to it. Just take my example:
You have two files, as mentioned in the question. Now you need to execute the files. It is as simple as that:
read the first line of scr.txt
check if it's a function. If not, skip the line
If yes, read the next line which tells the index where it's arguments are in arg.txt
pass on the index(an integer) to the "Call" function.
Now to the function which has to be executed, it should know how many arguments it needs. i.e 2
Lets say that the function is "Sum(a,b : integer)".It needs 2 arguments
Now let the function read the two arguments from arg.txt.
And its done!
I hope it will help you all.
And I can get some rep :)
i have a file with below data
this is a text file with html format $testarray['G']
i use this script but it is not work properly.
<?php $testarray=array();
$testarray['G']=100;
$result222 =file_get_contents(realpath('file.php'));
printf($result222);?>
i want this script, print out below line
this is a text file with html format 100
i do't want to use include or require function because user can insert php code in this file and i do't want user can use php codes in this file
can anybody help me?
many thanks
If you know the string you expect to perform a substitution on, you can always do it manually with str_replace(). However, it looks like you want to be able to substitute arbitrary variables into the string, which I implore you to not do. You are giving this PHP script way too much power as is. I can think of a few exploits off the top of my head, such as injecting superglobals among simply brute forcing variable names.
Edit: I realize now that I also didn't give you the straightforward answer which does as you request: the eval() function. You should be able to craft a string that assigns the contents of the file to a variable, which should perform variable substitutions by the PHP parser. Please don't use it, but if you do be very careful.
i used below script
$result222 =file_get_contents(realpath('file.php'));
$result222=str_replace(array("<?","?>")," ",$result222);
print eval("return<<<ENDEVAL\n$result222\nENDEVAL;\n");
this is my first time asking a question so let me know if I am doing something wrong (post wise)
I am trying to create a function that writes into a .txt but i seem to get two very different results between calling it from within a module, and writing the same loop in the shell directly. The code is as follows:
def function(para1, para2): #para1 is a string that i am searching for within para2. para2 is a list of strings
with open("str" + para1 +".txt", 'a'. encoding = 'utf-8') as file:
#opens a file with certain naming convention
n = 0
for word in para2:
if word == para1:
file.write(para2[n-1]+'\n')
print(para2[n-1]) #intentionally included as part of debugging
n+=1
function("targetstr". targettext)
#target str is the phrase I am looking for, targettext is the tokenized text I am
#looking through. this is in the form of a list of strings, that is the output of
#another function, and has already been 'declared' as a variable
when I define this function in the shell, I get the correct words appearing. However, when i call this same function through a module(in the shell), nothing appears in the shell, and the text file shows a bunch of numbers (eg: 's93161), and no new lines.
I have even gone to the extent of including a print statement right after declaration of the function in the module, and commented everything but the print statement, and yet nothing appears in the shell when I call it. However, the numbers still appear in the text file.
I am guessing that there is a problem with how I have defined the parameters or how i cam inputting the parameters when I call the function.
As a reference, here is the desired output:
‘She
Ashley
there
Kitty
Coates
‘Let
let
that
PS: Sorry if this is not very clear as I have very limited knowledge on speaking python
I have found the solution to issue. Turns out that I need to close the shell and restart everything before the compiler recognizes the changes made to the function in the module. Thanks to those who took a look at the issue, and those who tried to help.
