Python closures are function objects returned by another function. We use them to eliminate code redundancy.
In the example below, we’ve written a simple closure for multiplying numbers.
def multiply_number(num):
def product(number):
'product() here is a closure'
return num * number
return product
num_2 = multiply_number(2)
print(num_2(11))
print(num_2(24))
num_6 = multiply_number(6)
print(num_6(1))
The output is:
22
48
6
