how to loop through an array in python code example

Example 1: python loop through list

list = [1, 3, 6, 9, 12] 
   
for i in list: 
    print(i)

Example 2: iterate through an array python

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

Example 3: 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'
