Hi,
Does ctypes, when using restype, frees allocated memory?
For example, will the memory allocated by "strdup" be freed after the "del"
statement? If not, how can I free it?
---
import ctypes
libc = ctypes.cdll.LoadLibrary('libc.so.6')
strdup = libc.strdup
strdup.argtypes = [ctypes.c_char_p]

I've tried the following program and I'm more confused now :) Can anyone

No, of couse no
I have the following command below.
The overall aim is to allow the user to select a Y-value by pressing on the bar
graph. The colour of each bar should then change depending on what this Y-value
is.

import numpy as np
from scipy import stats

Thank you for the help! Based on your response/recommendation, I am
thinking that my entire approach to solving my problem is very poor. I am
trying to pull slices from a dataframe, store them in a nested dictionary,
retrieve them, perform calculations, store the results in the same nested
dictio
