for in python index code example

Example 1: python3 iterate through indexes

items=['baseball','basketball','football']
for index, item in enumerate(items):
    print(index, item)

Example 2: python access index in for loop

for index, item in enumerate(items):
    print(index, item)

#if you want to start from 1 instead of 0
for count, item in enumerate(items, start=1):
    print(count, item)

Example 3: python gt index in for cycle

my_list = [0,1,2,3,4]
for idx, val in enumerate(my_list):
    print('{0}: {1}'.format(idx,val))
#This will print:
#0: 0
#1: 1
#2: 2
#...

Example 4: python how to get index in for loop

# There are two ways to do this
# The "beginner" one:
index = 0
foods = ["burger", "pizza", "apple", "donut", "coconut"]
for food in foods:
  print("Food", index, "is", food)
  index += 1

# Or using enumerate:
foods = ["burger", "pizza", "apple", "donut", "coconut"]
for index, value in enumerate(foods):
    print("Food", index, "is", value)

# By convention, you should understand and use the enumerate function as it makes the code look much cleaner.

Example 5: for loop with index python3

colors = ["red", "green", "blue", "purple"]

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

Example 6: python enumerate for loop

presidents = ["Washington", "Adams", "Jefferson", "Madison", "Monroe", "Adams", "Jackson"]
for num, name in enumerate(presidents, start=1):
    print("President {}: {}".format(num, name))
