Use of 'continue' instruction in a 'while' loop - GJG - Dec-29-2020
Hi folks! I'm a beginner and at the moment I'm taking a course of loop control in python. One of examples of how to implement continue instruction in a loop was this:
largest_number = -99999999
counter = 0
number = int(input("Enter a number or type -1 to end program: "))
while number != -1:
if number == -1:
continue
counter += 1
if number > largest_number:
largest_number = number
number = int(input("Enter a number or type -1 to end program: "))
if counter:
print("The largest number is", largest_number)
else:
print("You haven't entered any number.")What I don't understand is why is it needed there at all? same for the if number == -1: condition? what function does it perform? and Isn't 'while' condition enough to carry out the task?while number != -1:
counter += 1seems to be working fine without them..?Thank you!

that code will never execute, you're right, it's not needed and is worthless.
the condition of the while clause is number not = -1
so
if number == -1 can never be satisfied.
