7. Looping over a collection

Avoid using an index to access your elements in the array.

7.1. Don’t do this

names = ['john', 'jane', 'jeremy', 'janice', 'joyce', 'jonathan']

for i in range(len(names)):
    print(names[i])

7.2. Do this

names = ['john', 'jane', 'jeremy', 'janice', 'joyce', 'jonathan']

for name in names:
    print(name)
