Python Day- 10 Looping

While Loop:
Example:1

no = 1
while no<=5:
    print(no, end=' ')
    no+=1

Enter fullscreen mode Exit fullscreen mode

Output:

1 2 3 4 5 
Enter fullscreen mode Exit fullscreen mode

Example:2

1) 1 2 3 4 5 6 7 8 9 10
2) 10 9 8 7 6 5 4 3 2 1
3) 1 3 5 7 9
4) 2 4 6 8 10
5) 3 6 9

#1 2 3 4 5 6 7 8 9 10
no = 1
while no<=10:
    print(no, end=' ')
    no+=1

print(end='\n')

# 10 9 8 7 6 5 4 3 2 1
no = 10
while no>=1:
    print(no, end=' ')
    no-=1

print(end='\n')

# 1 3 5 7 9 
no = 1
while no<=10:
    print(no, end=' ')
    no+=2

print(end='\n')

#2 4 6 8 10
no=2
while no<=10:
    print(no, end=' ')
    no+=2

print(end='\n')

# 3 6 9
no = 3
while no<=10:
    print(no, end=' ')
    no+=3
Enter fullscreen mode Exit fullscreen mode

Output:

1 2 3 4 5 6 7 8 9 10 
10 9 8 7 6 5 4 3 2 1 
1 3 5 7 9 
2 4 6 8 10 
3 6 9
Enter fullscreen mode Exit fullscreen mode

Example:3 (using *)

no = 1
while no<=5:
    print(no*3, end=' ') 
    no+=1
Enter fullscreen mode Exit fullscreen mode

Output:

3 6 9 12 15
Enter fullscreen mode Exit fullscreen mode

Example:4(5 tables-->1*5=5 upto 10*5=50)

Input can be given in 2 ways,

Input: 1

no = 1
while no<=10:
    print(no,"*5=",no*5, end='\n')
    no+=1

Enter fullscreen mode Exit fullscreen mode

Input: 2 (Using f string-formatted string literal)
-->A formatted string literal or f-string is a string literal that is prefixed with f or F.
-->Expressed using curly braces {}.
-->It is used to look at the values , expressions or instance inside {} and substitute them with the variables values or results.

no = 1
while no<=10:
    result=no*5
    print(f'{no} * 5 = {result}')
    no+=1
Enter fullscreen mode Exit fullscreen mode

Output of both inputs:

1 * 5 = 5
2 * 5 = 10
3 * 5 = 15
4 * 5 = 20
5 * 5 = 25
6 * 5 = 30
7 * 5 = 35
8 * 5 = 40
9 * 5 = 45
10 * 5 = 50

Enter fullscreen mode Exit fullscreen mode

Example:5

#1  2   3   4   5   5   4   3   2   1

no = 1

while no <= 5:  
    print(no, end=" ")
    no += 1

no = 5
while no > 0:  
    print(no, end=" ")
    no -= 1
Enter fullscreen mode Exit fullscreen mode

Output:

1 2 3 4 5 5 4 3 2 1
Enter fullscreen mode Exit fullscreen mode

Example:6

#1  3   5   7   9   2   4   6   8   10

no = 1
while no<=10:
    print(no, end = ' ')
    if no==9:
        no = 0
    no+=2
Enter fullscreen mode Exit fullscreen mode

Output:

1 3 5 7 9 2 4 6 8 10
Enter fullscreen mode Exit fullscreen mode
