How to do while loops with multiple conditions?

Question

I have a while loop in python condition1=False condition1=False val = -1 while condition1==False and condition2==False and val==-1: val,something1,something2 = getstuff() if something1==10: condition1 = True if something2==20: condition2 = True ' ' I want to break out of the loop when all these conditions are true, the code above does not work I originally had while True: if condition1==True and condition2==True and val!=-1: break which works ok, is this the best way to do this? Thanks

Answer 1

Hi there!

I hope this video helps answer your question.

If you would like to post the code that is in the getstuff() function, I could take a look at that as I believe that is why your original code is not working properly.

Answer 2

condition2 is not getting initialized; you have condition1 listed TWICE before the while loop

how are these variables getting set? you have three variables with 2 commas in the

same assignment statement

function getstuff() can only return one value, unless it makes multiple calls or you pass

the other vars by reference

lastly, val = -1 will get treated as true because zero is false

================================================================

You can rewrite the loop like this:

something1=something2=val = 0 // they are all false

while (something1 != 20) and (something2 != 10) and (val ==0)

//* MUST get the value for something1, something2, and val INSIDE the loop

something1 = .....

something2 = ....

val = .......

end while
