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

python access index in for loop

for index, item in enumerate(items):

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

python for with iterator index

for index, value in enumerate(iterator):
    print(index, value)

for loop with index python3

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

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

python iterate with index

for index, item in enumerate(iterable, start=1):

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))

python loop index and value

l = ["val1", "val2","val3"]
for i, value in enumerate(l):
  print(f'Index= {i}, value= {value}')

for loop with index python

presidents = ["Washington", "Adams", "Jefferson", "Madison", "Monroe", "Adams", "Jackson"]

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))
