'int' object has no attribute 'strip' error message

问题

This is my program and what means this error?

def menuAdiciona():
    nome = input("Digite o nome de quem fez o cafe: ")
    nota = int(input("Que nota recebeu: "))

    if len(nome.strip()) == 0:
        menuAdiciona()

    if len(nota.strip()) == 0:
        menuAdiciona()

    if nota < 0:
        nota = 0

AttributeError: 'int' object has no attribute 'strip'.

回答1:

You are trying to call strip() on the nota value, which is an integer. Don't do that.

回答2:

If you have a case for which you don't know whether the incoming value is a string or something else, you can deal with this using a try...except:

try:
    r = myVariableOfUnknownType.strip())
except AttributeError:
    # data is not a string, cannot strip
    r = myVariableOfUnknownType

回答3:

integer has no strip attribute... so you can make it like this...

if len(str(nome).strip()) == 0:
    menuAdiciona()

if len(str(nota).strip()) == 0:
    menuAdiciona()

回答4:

strip is only available for strings

if you desperately need to strip numbers try this:

str(nome).strip()

str(nota).strip()

so it turns out to be:

def menuAdiciona():
nome = input("Digite o nome de quem fez o cafe: ")
nota = int(input("Que nota recebeu: "))

if len(str(nome).strip()) == 0:
    menuAdiciona()

if len(str(nota).strip()) == 0:
    menuAdiciona()

if nota < 0:
    nota = 0
