Need help with NumPy Histogram function coding

[Triikey]

Hi, I'm a student currently doing experimental work in a lab and need to analyse some data. The data includes sniffing data from animals and I need to plot out sniffing rate. My mentor told me to use the NumPy Histogram function to do it, but I'm running into some struggles. The assignment is the following:


# calculate for each trial how many inhalations were performed in 0,5 bins
# trials are found in single ses_ids
# look up function np histogram
# then calculate mean sniffing across time for all trials and plot it


What I have already got so far is:

import matplotlib.pyplot as plt
import numpy as np
import os

data_path = r'C:\Users\32487\OneDrive\Documenten\Internship_data_KK4748'
ses_ids = ['230317_KK047', '230317_KK048']

for ses_id in ses_ids:
    ses_path = os.path.join(data_path, ses_id)
    print(ses_path)
    hist, bin_edges = np.histogram([ses_path], bins = range(10))
    print(hist)
    print(bin_edges)

What I want to do but can't is:


# how can I arrange bins to be 0,5 interval and how can I make the range fit the data?
# how can I make my path go INTO the ses_id and pick individual trials from there?
# how can I plot the histogram then? I think it's something like:

plt.hist([ses_path])
plt.show()

So basically with the function I have, I get the histogram [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], because I put the range at 10, and I did not make my path go into my file folder with the data (which I don't know how to do) but rather into the general named folder.

Any help is appreciated!

Please, use proper tags when post code, traceback, output, etc. This time I have added tags for you.
