Is there no const constant keyword in Python?

Python has no constant keyword, so there is no constant declaration. Instead, there is a rule that names of constants are all capitalized and underlined (_), which warns you if most editors assign something to a variable in an uppercase name.

Java's public static final string CONST_NAME = "Name"; is replaced by Python.

class Foo(object):
    CONST_NAME = "Name"

#or
CONST_NAME = "Name"

This is.
