python3 iterate through indexes

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

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)

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):
   print index, item

python for loop with index

colors = ["red", "green", "blue", "purple"]
for i in range(len(colors)):
    print(colors[i])

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"]
for i in range(len(presidents)):
    print("President {}: {}".format(i + 1, presidents[i]))

python loop with index

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

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))
