Example
Find the total number of possibilities to choose k things from n items:
# Import math Library
import math
# Initialize the number of items to choose from
n = 7
# Initialize the number of possibilities to choose
k = 5
# Print total number of possible combinations
print (math.comb(n, k))
The result will be:
21

Definition and Usage
The math.comb() method returns the number of ways picking k unordered outcomes from n possibilities, without repetition, also known as combinations.
Note: The parameters passed in this method must be positive integers.
Syntax
