'''how to use range() function in for loop - 
here range 0 is inclusive I mean 0 will print it will start from 0
and 4 is exclusive I mean 4 will not print, it will stop to number 3
'''

# for number in range(11):
#     print(f'Number is : {number}')
    
'''How to print specific number within range
we can specify start and end.
here number 1 is inclusiveand
number 10 is exclusive
'''
# for number in range(1, 10):

'''range() function another use
specify start, end, increment
'''

# for number in range(2, 20, 2):
#     print(f'Number is :{number}')
    
'''How to print out the index of the items
we can use buit in function enumerate
'''

# for index, fruit in enumerate(my_fruits_list):
#     print(f'Fruit :{fruit} is at index no : {index}')
    
'''how to use for loop in dictionary'''
