range can be used to loop over a sequence of integers.

#!/usr/bin/python
for item in range(5):
  print(item)

This most basic script should output 0 through 4.

0
1
2
3
4

You can specify the beginning integer (0 in this example) and the ending integer (5 in this example).

#!/usr/bin/python
for item in range(1, 5):
  print(item)

Which should output 1 through 4.

1
2
3
4

You can specify the count that should be incremented in each loop (2 in this example).

#!/usr/bin/python
for item in range(1, 10, 2):
  print(item)

Which should output the following.

0
2
4
6
8

Or you could use an if else statement to match every other result.

#!/usr/bin/python3
for item in range(1, 11):
  #print(item)
  if (item % 2):
    print(f"{item} was matched by the if statement")
  else:
    print(f"{item} was matched by the else statement")
