How to find if the function exist in python

there are several ways to find the corresponding functions of on Object, the one I have been using often is 'dir':

import matplotlib.pyplot as plt
fig = plt.gcf()
dir(fig)

Now suppose, that I have an idea how the function is called; for example, it’s set_size***. In this case, though, I am not completely sure if it’s set_size_inches or set_size_inch.

Is there any way that I could provide my partial piece of information to figure out the complete correct name of the function?

Something like:

hasattr(fig, set_size*)

You could probably use inspect module for it and filter through it but honestly, the best way is probably google or documentation

You can find all module's members like this

[fn for fn in fig if fn.startswith('set_size')]

So you can get module function

fn_name = [fn for fn in fig.__dict__.keys() if fn.startswith('set_size')][0]
fn = getattr(fig, fn_name)
