print 返回地址而不是值

Question

我是 python 的新手，我正在嘗試打印此函數，但它只顯示函數的地址。

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，任何東西都是對象，這包括函數。 當您打印一個函數時，您會得到該函數的地址。

由於您希望eligible的函數返回字符串，因此需要將結果存儲在變量中或將函數調用放入print函數中：

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

Answer 2

刪除最后一行並將eligible(age, language, planguage)放入print語句中。

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

您可以稍微更改代碼的最后一行：

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))

希望這對你有幫助，謝謝！
