Today I learned a better way to loop through parallel lists in Python

Better Loop Pattern for Parallel Lists.py

L = ['value', 'value2', 'value3']
L2 = ['value', 'value2', 'value3']

# Old-Old way
for index in range(len(L)):
    item = L[index]
    item2 = L2[index]
    print(item, item2)

# Old way
for index, item in enumerate(L):
    item2 = L2[index]
    print(item, item2)

# New way
for item, item2 in zip(L, L2):
    print(item, item2)
