I want to make it like this: (sorted number '1-3' instead of '0-2')

1. name John
2. age 20
3. gender Male

Answer 1

You can use enumerate with its start argument, it's literally made for this:

for i, (key, value) in enumerate(my_lib.items(), start=1):
    print(i, key, value)

Answer 2

Try this:

for i, (x, y) in enumerate(my_lib.items()):
    print(i+1, x, y)
