Help i am unable to run my code in code 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 need a 'break' statement to terminate your while loop as soon as the result is printed, otherwise it would continue taking input and printing the text forever.

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)
break
elif userin == "sub":
print("result is " + resultsub)
break
elif userin == "mul":
print("result is " + resultmul)
break
elif userin == "div":
print("result is " + resultdiv)
break

Alternatively, you could add a single break after all then conditional statements.
