Python naming convention for variables that are functions

Question

Does Python have a naming convention for variables that are functions? I could not see anything specific for this in PEP-8 (except for variable names).

Since functions are first-class objects in Python, _fndoes it use a suffix or something similar, a recognized convention?

EDIT : updated with a more realistic example

Example:

def foo_a():
    print 'a'

def foo_b():
    print 'b'

funcs = {'a': foo_a, 'b': foo_b}

# dynamically select function based on some key
key = 'a'
foo_fn = funcs[key]

No, it’s not, functions are first class objects in Python. Pass the name of the function as you will gain access to it for calling.

For instance:

def foo():
    pass

foo() # calling

another_function(foo) # passing foo

- . , , , , . :

def do_nothing():
    pass

EDIT: , _fn , :

def foo_a():
    print 'a'

def foo_b():
    print 'b'

funcs = {'a': foo_a, 'b': foo_b}

# dynamically select function based on some key
key = 'a'
foo_fn = funcs[key]

foo_fn() # calling
another_function(foo_fn) # passing
