print 返回地址而不是值

Question

我是 python 的新手，我正在尝试打印此函数，但它只显示函数的地址。

def eligible(age, lingo, language):
    return "Eligible!" if(int(age) in range(25, 46)) and (lingo=='ingles') and (language=='python') else "Not Eligible!"

age=input("What's your age?: ")
language=input("What language do you speak?: ")
planguage=input("What programing language do you use?: ")
eligible(age, language, planguage)

print(eligible)

Answer 1

在 Python 中，任何东西都是对象，这包括函数。 当您打印一个函数时，您会得到该函数的地址。

由于您希望eligible的函数返回字符串，因此需要将结果存储在变量中或将函数调用放入print函数中：

res = eligible(age, language, planguage)
print(res)
print(eligible(age, language, planguage))

Answer 2

删除最后一行并将eligible(age, language, planguage)放入print语句中。

def eligible(age, lingo, language):
    return "Eligible!" if(int(age) in range(25, 46)) and (lingo=='ingles') and (language=='python') else "Not Eligible!"

age=input("What's your age?: ")
language=input("What language do you speak?: ")
planguage=input("What programing language do you use?: ")
print(eligible(age, language, planguage)) # Print Statement here

Answer 3

您可以稍微更改代码的最后一行：

def eligible(age, lingo, language):
    return "Eligible!" if(int(age) in range(25, 46)) and (lingo=='ingles') and (language=='python') else "Not Eligible!"

age=input("What's your age?: ")
language=input("What language do you speak?: ")
planguage=input("What programing language do you use?: ")
print(eligible(age, language, language))

希望这对你有帮助，谢谢！
