A while loop

while loops are used when a specific task is supposed to be executed until a specific condition is met. while loops are commonly used to execute code in an infinite loop. Let's look at a specific example where we would like to print the value of i from 0 to 9:

i=0 while i<10:   print("The value of i is ",i)   i+=1

Inside the while loop, we increment i by 1 for every iteration. The value of i is incremented as follows:

i += 1

This is equivalent to i = i+1.

This example would execute the code until the value of i is less than 10. It is also possible to execute something in an infinite loop:

i=0 while True:   print("The value of i is ",i)   i+=1

The execution of this infinite loop can be stopped by pressing Ctrl + C on your keyboard. ...
