Use `math.prod` instead of multiplying in a loop

Python pattern

This pattern transforms a loop that computes the product of a list of numbers into a call to math.prod (introduced in Python 3.8).

Apply with the Grit CLI
grit apply math_prod

Transforms for loop to math.prod

BEFORE 
from math import log

n = 1
for x in range(10):
    n *= x

n = 1.0
for x in range(10):
    n = n * x

n = 1
for x in range(10):
    n = x * n

prod = 1
for x in [4, 5, 6]:
    prod *= x

# Left as is

n = 1
for x in range(10):
    y = n * x

n = 1
for x in range(10):
    n = y * x

n = 1
for x in range(10):
    n *= x
    print("multiplied")
AFTER 
import math

from math import log

math.prod(range(10))

math.prod(range(10))

math.prod(range(10))

math.prod([4, 5, 6])

# Left as is

n = 1
for x in range(10):
    y = n * x

n = 1
for x in range(10):
    n = y * x

n = 1
for x in range(10):
    n *= x
    print("multiplied")
