# Print 1 to 100 in Python Using For Loop & While Loop

In this post, we will discuss how to print 1 to 100 numbers in Python using for loop and while loop. Also, develop a program to print 1 to 100 without a loop in Python.

We will take a range from 1 to 101. Then, print all numbers in an interval 1 to 101 using the For Loop.

# Python program to print numbers from 1 to 100

print('Numbers from 1 to 100:')
for n in range(1, 101):
print(n, end=' ')

Output:-

Numbers from 1 to 100:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100

In the previous program, we used for loop to print 1 to 100 but In this program, we are using the while loop to print 1 to 100 numbers.

# Python program to print numbers from 1 to 100

print('Numbers from 1 to 100:')
n = 1
while n <= 100:
print(n, end=' ')
n = n+1

Output:-

Numbers from 1 to 100:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100

This python program also performs the same task but in this program, we are print 1 to 100 without a loop. To solve this problem, we can use recursion techniques.

A method that contains a call to itself is called the recursive method. A technique of defining the recursive method is called recursion. The recursive method allows us to divide the complex problem into identical single simple cases that can be handled easily. This is also a well-known computer programming technique: divide and conquer.

# Python program to print numbers from 1 to 100

def print_num(n):
if n > 0:
print_num(n - 1)
print(n, end = ' ')

print('Numbers from 1 to 100:')
print_num(100)

Output:-

Numbers from 1 to 100:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100
