  print(i); 
  #output: 1,3,5,7,9
  
for i in range (1,4): # (initial, final but not included)
  print(i);
  #output: 1,2,3 note: 4 not included

for i in range (5):
  print (i);
  #output: 0,1,2,3,4 note: 5 not included

python = ["ml","ai","dl"];  
for i in python:

for letter in letters:
  print(letter) # prints a, b, c
  
# Dictionaries:
letters = {'a': 1, 'b': 2, 'c': 3}
for letter, num in letters.items():
  print(letter, num) # prints a 1, b 2, c 3

loop in python

# A Sample Python program to show loop (unlike many 
# other languages, it doesn't use ++) 
# this is for increment operator here start = 1,  
# stop = 5 and step = 1(by default) 
print("INCREMENTED FOR LOOP") 
for i in range(0, 5): 
   print(i) 
  
# this is for increment operator here start = 5,  
# stop = -1 and step = -1  
print("n DECREMENTED FOR LOOP") 
for i in range(4, -1, -1): 
   print(i)
