Brainy Fact
When there is no change of condition in while loop then it becomes infinite loop, For example,
i=1
while i<6:
print(i)
In the above code, the value of i will always be 1, and due to this, the condition will always be
True and will keep on executing the statement inside for an infinite number of times.
The different examples of while loop are:
Commands Output
count=1 hello
while count<=5: hello
print("hello") hello
count+=1 hello
print("Program ends") hello
Program ends
i = 1 1
while i < 6: 2
print(i) 3
i += 1 4
5
"""Input a number and check for even or odd. enter a number: 3
The whole process should continue till the user wants""" 3 is Odd
ans = "y" Press 'y' to continue: y
while ans=="y": enter a number: 6
num=int(input("enter a number:")) 6 is Even
if num%2==0: Press 'y' to continue: y
print(num," is Even") enter a number: 12
else: 12 is Even
print(num," is Odd") Press 'y' to continue: n
ans=input("Press 'y' to continue:") Program ends here
print("Program ends here")
