While loop using python

Guide Kit

For executing the block each time, the Python for statement iterates over the members of a sequence in order. A condition must be checked each time or repeat a block of code forever, contrasting the for statement with the ''while'' loop used. For example: Running 3 times for a loop from 0 to 2. Like in the while loop, we can combine else statements with for loops. The execution will terminate, so after for block finishes execution, the else block will be executed immediately.

We can run a set of statements if a condition is true with the while loop. The break statement can stop the loop if the while condition is true. We can stop the present iteration and continue with the next with the continue statement. We can run a code block once when the condition is no longer true with the else statement.

With loops, we can execute a block of code repeatedly In programming. For example, a loop can show a message 100 times. This is a simple example; we can achieve much more with loops.

We can evaluate the condition using a while loop.
Inside the while loop, the code is executed., If the condition is True.
The condition is evaluated again.
Until the condition is False, this process continues.
The loop stops When the condition evaluates to False.
The loop runs for infinite times (till the memory is full) if a loop's condition is always True.

age = 1  # simply intializing value for 1st condition to be True

# loop will break if you enter 0
while True:
    age = int(input("Please enter your age(Enter 0 to quit): "))
    if age == 0:
        break
    if age < 3:
        print("Your ticket is free")
    elif age > 12:
        print("your Ticket cost $15")
    else:
        print("your Ticket cost $10")
