Python partial function

Partial function

The function of functools.partial is to fix certain parameters of a function (that is, to set the default value
def int2 (x, base=2):
return int (x, Base)

>>> Import Functools
>>> Int2 = functools.partial (int, base=2)

When a function has too many arguments and needs to be simplified, use functools.partial to create a new function that can fix some of the parameters of the original function, making it easier to call

Max2 = Functools.partial (max, 10)
Will actually automatically add 10 as part of the *args to the left, namely:

MAX2 (5, 6, 7)
Equivalent:
args = (10, 5, 6, 7)
Max (*args)
The result is 10.
