How to Eliminate Nested Loops for Parameter Combinations in Code?

Eliminating Nested Loops for Parameter Combinations

When testing code with numerous parameter combinations, the use of nested for loops can result in convoluted code. Fortunately, there are methods to circumvent this depth.

Utilizing itertools.product

The itertools.product function can be employed to generate combinations without nesting. Here's an illustration:

x1 = range(min1, max1, step1)
x2 = range(min2, max2, step2)
x3 = range(min3, max3, step3)
...

for v1, v2, v3, v4, v5, v6 in itertools.product(x1, x2, x3, x4, x5, x6):
    do_something_with(v1, v2, v3, v4, v5, v6)

A more condensed version is presented below:

ranges = [
    range(min1, max1, step1),
    range(min2, max2, step2),
    range(min3, max3, step3),
    ...
]

for v1, v2, v3, v4, v5, v6 in itertools.product(*ranges):
    do_something_with(v1, v2, v3, v4, v5, v6)
