python iterate list and index code example

Example 1: how to iterate over a list in python with index

# Create the list
my_list = [1, 2, 3]

# Python automatically creates an index for you and increments it for you
for index in range(len(my_list)):
  print(my_list[index])

Example 2: iterating with index in for loops python

colors = ["red", "green", "blue", "purple"]
ratios = [0.2, 0.3, 0.1, 0.4]
for color, ratio in zip(colors, ratios):
    print("{}% {}".format(ratio * 100, color))
