The input takes numbers until a negative number is entered, every number before that is multiplied by 2 and the result is printed and formatted to the 2nd digit after the comma. I've tried the following, however the loop just continues endlessly giving me only 1 result, how can I make it stop and multiply with the next input instead?
x = float(input())
while x > 0:
result = x * 2
if x < 0:
print('Negative number!')
print(f'Result: {result:.2f}')
CodePudding user response:
There are many issues with your code. Here's the fixed version:
while True:
x = float(input("Input: "))
if x < 0:
print('Negative number!')
break
else:
result = x * 2
print(f'Result: {result:.2f}')
"break" is needed to interrupt the while loop on the first bad result.
