How to do a graph in Python? (and proper terminology)

[jpy]

Hi everyone - I have a few questions I hope you can help me with.

1. I am using Pandas and NumPy, are these called libraries?
   Is there somewhere I can see a list of all functions with what they do? I am focusing on using Excel within Python.
   
   

I also ran the code below:

pd.value_counts(excl['Pop']).plot.bar()

This code works but the graph is the same all across when it shouldn't. I would like to sum all values found in the 'Pop' column and group by the 'State' column.

Yes, they are libraries.
Pandas documentation: https://pandas.pydata.org/pandas-docs/st...index.html
Numpy reference: https://numpy.org/doc/stable/reference/index.html
Graphing with matplotlib: https://matplotlib.org/3.3.3/contents.html

These are big topics, there are a number of books written about Pandas/Numpy/Matplotlib/Scikit-Learn

In Python they are often called modules, but libraries would be the same.
To make a graph in Python you have several options like matplotlib, plotly, bokeh, seaborn, altair and pygal. Matplotlib is one of the more popular modules. Some examples: matplotlib, seaborn, altair, plotly

Not sure if I understand correctly, but Pandas has a sum value, you can fetch all values like this

X = df['B']

where B is your column name. Then call sum() on it
