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 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 4: for loop with index python3
colors = ["red", "green", "blue", "purple"]
for i in range(len(colors)):
print(colors[i])
Example 5: python for loop index
presidents = ["Washington", "Adams", "Jefferson", "Madison", "Monroe", "Adams", "Jackson"]
for num, name in enumerate(presidents, start=1):
print("President {}: {}".format(num, name))
Example 6: python for loop index
# Creates two variables; An index (num), and the value at that index (line)
for num, line in enumerate(lines):
print("{0:03d}: {}".format(num, line))
