Equality in Python

Some facts, that not many people knows:

for i in range(100):
#   ^ assignment to name i
    pass

with open('some_file.txt') as fd:
#                             ^^ assignment to name fd
    pass

[x for x in range(100)]
#      ^ assignment to name x

def foo(a, b):
#   ^^^ assignment of the function to the name foo
#       ^ assignment to name a
#          ^ assignment to name b
    pass

class Foo:
#     ^^^ assignment of class to name Foo
    pass

What we call variables, are just names. We assign an object (lives somewhere in memory) to a name.
