Why are Python lambdas useful? [closed]

Answer 1

I use lambda to create callbacks that include parameters. It's cleaner writing a lambda in one line than to write a method to perform the same functionality.

For example:

import imported.module

def func():
    return lambda: imported.module.method("foo", "bar")

as opposed to:

import imported.module

def func():
    def cb():
        return imported.module.method("foo", "bar")
    return cb
