Reduce nested for i in range(n) loops to a single line

mrange

Install via pip install mrange

Import via from mrange import mrange

Description

mrange is used to remove nested range loops

Input:

n_s = (n_1, n_2, ..., n_m) Tuple of integers

Output:

Generator outputting len(n_s) values with every call, generating every combination of values in the intervals [0,1,...,n_s[i]-1]

Use:

for a, b, ..., m in mrange((n_a, n_b, ..., n_m)):
    ...
Replaces:
for a in range(n_a):
    for b in range(n_b):
       ...
           for m in range(n_m):
               ...
