How to get the source code of a Python function?

Sometimes, we want to get the source code of a Python function.

In this article, we’ll look at how to get the source code of a Python function.

To get the source code of a Python function, we can use the inspect.getsource method.

For instance, we write:

import inspect


def foo(arg1, arg2):
    a = arg1 + arg2
    return a


lines = inspect.getsource(foo)
print(lines)

We create the foo function that we want to get the code for into a string.

To do that, we call inspect.getsource with foo and assign the code string to lines.

Therefore, lines is:

def foo(arg1, arg2):
    a = arg1 + arg2
    return a

To get the source code of a Python function, we can use the inspect.getsource method.
