[SOLVED] I don't understand why the print() does nothing, please, explain me:

Question

[RESUELTO] No entiendo por qué el print() no hace nada, por favor, expliquenme:

def decor(num):
def printing(fun):
print("***")
print(f"INVOICE #{fun}")
print("***")
print("END OF PAGE")
return printing
@decor
def invoice(num):
print()
invoice(input())

Answer 1

num in the decor refers to invoice function that you didn't call in the decor function

check the difference here

def decor(num):
def printing(fun):
print("***")
print(f"INVOICE-123 #{fun}")
num(fun)
print("***")
print("END OF PAGE")

return printing

@decor
def invoice(num):
print("INVOICE #" + num)

invoice(input())

Answer 2

Hi ★«Caleb Guerra Ortega»★
you just need to add the print statement with output the num with statement below is your fixed code..

def decor(num):
def printing(fun):
print("***")

print(f"INVOICE #{fun}")
print("***")
print("END OF PAGE")
return printing
@decor
def invoice(num):
print("INVOICE #" +num)
invoice(input())
