Why i can't run it in playground.

Question

while True:
print("add for addition")
print("sub for substraction")
print("mul for multiplication")
print("div for division")
userin = input(": ")
x = float(input("a:"))
y = float(input("b:"))
resultadd = str(x + y)
resultsub = str(x - y)
resultmul = str(x * y)
resultdiv = str(x / y)
if userin == "add":
print("result is " + resultadd)
elif userin == "sub":
print("result is " + resultsub)
elif userin == "mul":
print("result is " + resultmul)
elif userin == "div":

Answer 1

You could also have:
1. invisible control characters from copy+pasting and
2. you may need to separate your inputs with enter in the input dialog.

Answer 2

It depends on what's happening ... I can think of 3 things to check and want to narrow the field.

What do you see? Can you post a code link so we can look?

Answer 3

As posted, your missing the statement required by the "div" elif. You should have a userin value to exit the infinite loop. The fact that you perform all operations prevents my adding 5 & 0 as a divide by zero will occur.

it was a mistake....(during copy paste)
actually I wrote my code in a app named pyroid ....there I can it run
