while true and if statements

[Enderg312]

I am trying to loop my program with a while true but I have an if statement in there and if I type close it is suppose to close it and with the while true it wants to ignore the close part. How to I allow my program to loop and close when I type close? 

And it is python coding.

You can use break to stop executing a loop, like e.g.:

while True:
	if(someconditionhere):
		break

Can you explain more because all that is doing is stopping the while True altogether?

Eternal loops can only be stopped if you apply a inner if/else statement. so like @WereCatfexplained:

inpt = input("What do you want? ")
while True:
    if inpt == "close":
        print("looped stop")
        break # You can also use sys.exit() to terminate the whole program
    else:
    	# If the input insnt close you dont want to lock the loop
        inpt = input("What do you want? ")

The else part is not "mandatory" but if you want to have always a way to trigger that if

Why not just make a Boolean for your while loop and then set it to false when you want it to stop?

This is also my preferred method. In a simple program like this, it usually goes something like:

stopMe = False
while not stopMe:
  myVar = GetUserInput()
  if myVar == "stop":
    stopMe = True
    
  else if myVar == "go":
    MyGoFunc()
    
  else if myVar == "andOnandOn":
    MyOtherFuncs()
    
EndOfLoopFuncs()

The standard user input loop is:

1. Get input
2. Parse Input
3. Operate on Input
4. Goto Step #1
