How could I implement this code so that if I type "a" as 0 the program stops immediately and the message "END" appears?

def conta(x,y,z):
     return (a**b)+c


a = int(input('Infome a: '))
if a == 0:
    print('FIM')
b = int(input('Infome b: '))
c = int(input('Infome c: '))

result = conta(a,b,c)
print(result)

  • Ignore the "N" at the end of the question...

  • stop in order to pause, or terminate the program? To terminate the program immediately you can invoke the function exit(0).

Add an Else. Your code will look like this:

def conta(x,y,z): 
    return (a**b)+c

a = int(input('Infome a: ')) 
if a == 0: 
    print('FIM')
else:
    b = int(input('Infome b: ')) 
    c = int(input('Infome c: '))
    
    result = conta(a,b,c) 
    print(result)

That way you can:

def conta(x,y,z):
     return (a**b)+c

a = int(input('Infome a: '))
if a != 0:
    b = int(input('Infome b: '))
    c = int(input('Infome c: '))
    result = conta(a,b,c)
    print(result)
else:
    print('FIM')

'I pulled the result = conta(a,b,c) and the print(result) into the if, hence they will only be executed if it is non-zero.

Code change as jsbueno suggested:

import sys

def conta(x,y,z):
     return (a**b)+c

a = int(input('Infome a: '))
if a != 0:
    b = int(input('Infome b: '))
    c = int(input('Infome c: '))
    result = conta(a,b,c)
    print(result)
else:
    print('FIM')
    sys.exit(0)

If you are using Anaconda you may present a message at the end of the execution.

    This form is more elegant - but pegutna realemtne requires information that is missing there to be complete: to terminate a Python program at an arbitrary point it must be called sys.exit(0) (preceded by a import sys) - Can you add that to your reply? Then it’s complete for the next readers.
