I want to make a plot with the data am fetching from the database, voltage(float), and time(time), I was getting the error now am stack. please help or is there a best way I can go about it.?
import matplotlib.pyplot as plt
import numpy as np
import serial as ser
import time
import datetime
import mysql.connector
my_connect = mysql.connector.connect(host="localhost", user="Kennedy", passwd="Kennerdol05071994", database="ecg_db", auth_plugin="mysql_native_password")
mycursor = my_connect.cursor()
voltage_container = []
time_container = []
def fetch_voltage():
pat_id = 1
query = "SELECT voltage, time FROM ecg_data_tbl where patient_id = 1 "
mycursor.execute(query)
result = mycursor .fetchall()
voltage, time = list(zip(*result))
for volts in voltage:
voltage_container.append(volts)
voltage_data = np.array(voltage_container)
for tim in time:
time_container.append(tim)
time_data = np.array(time_container)
plt.plot(time_data, voltage_data)
fetch_voltage()
I was told to convert them to arrays which I did but nothing is changing. The error am getting is:

TypeError: float() argument must be a string or a number, not 'datetime.timedelta'
Your time data is not a type matplotlib is familiar with so it's trying to convert it itself and it can't. Instead make it a type it can handle yourself.
A common choice, for example, would be
for tim in time:
time_container.append(tim.total_seconds())
time_data = np.array(time_container)
Now you are using the total number of seconds in your datetime.timedelta object (that is the result of your query). This is a float so matplotlib can plot it. If you don't want total seconds you can look at the docs for other options.

I want to turn my database into sqlite3 for pandas df

Is there something wrong with this code? What is the reason for this error?
SQLALchemy 0.7.10 is really really old. Like 6.5 years old. It used time.clock which ...

Having assignment "Extracting Data With Regular Expressions". For this I'm importing regex, but the code is not working. what is my mistake?
I checked the code without "import", it does work. Lines 2-7 are working. But it got a traceback error on "import re" line 1.

fname = input('Enter file: ')
if len(fname) < 1 : fname = "sample.txt"

Because you have called your file re.py, the import will actually import this file instead of the built-in module for regular expressions.
Just rename your file to something different and it should work as expected.
Here are a few lines of code:

return getattr(var, attribute)
I was doing it from: mlxtend association_rules and apriori docs
As the error says: Series.strides are deprecated.
So how can I find the length of each frozenset in series? i.e. do same as above?

I use Python 3.4 [wrong: 3.5] with pandas 0.2 when the error occured. The same code on Python 3.6 with pandas 0.2 runs without problems on another work station. Anybody any idea how I can fix the error.
I allready tried to uninstall and to reinstall pandas and pandas-datareader but it didn't helped.
