for loop in python for an array code example

Example 1: iterate through an array python

colors = ["red", "green", "blue", "purple"]
i = 0
while i < len(colors):
    print(colors[i])
    i += 1

Example 2: python for loop with array

foo = ['foo', 'bar']
for i in foo:
  print(i) #outputs 'foo' then 'bar'
for i in range(len(foo)):
  print(foo[i]) #outputs 'foo' then 'bar'
i = 0
while i < len(foo):
  print(foo[i]) #outputs 'foo' then 'bar'
