Python：調用函數內部時發生錯誤

-1

我已經使用python製作了一個簡單的字典程序。Python：調用函數內部時發生錯誤

dictionary = {"testword" : "testmeaning"} 
y = ["y", "Yes", "Y", "YES", "yes", "yep", "YEP", "Yep"] 
n = ["n", "No", "N", "no", "NO", "nope", "Nope", "NOPE"] 

def ans(): 
    ans = raw_input("Y/N") 
    if ans in y: 
     meaning = raw_input("Type the meaning.") 
     dictionary[x] = meaning 
     print "Added!. Thanks for using the dictionary." 
     reload 
    elif ans in n: 
     print "Thanks for using the dictionary." 
    else: 
     print "Type either Y or N." 
     ans() 

def add_word(): 
    print "Do you want to add it?" 
    ans() 
def close_ans(): 
    close_ans = raw_input("Y/N") 
    if close_ans in y: 
     quit 
    elif close_ans in n: 
     in_dict() 
    else: 
     print "Type either Y or N" 
     close_ans() 

def close(): 
    print "Close?" 
    close_ans() 

def in_dict(): 
    global x 
    x = raw_input("Type the word.") 
    if x in dictionary: 
     print dictionary[x] 
     close() 
    else: 
     print "This word isn't in the dictionary yet." 
     add_word() 
     close() 

in_dict()

該代碼是非常明顯的。我用一個名爲「testword」的詞做了一個字典，其值爲「testmeaning」。還有一個正面和負面答案的列表，將用於確定用戶在某些情況下是否同意或拒絕。它首先調用函數in_dict，要求用戶輸入單詞。如果單詞在詞典中，則它打印含義並要求關閉。如果不是，它詢問用戶是否想要添加它。如果你不理解它，再次查看代碼。如果用戶輸入其他的東西，然後再輸入列表y或n中的單詞，它會再次提問。但是，它不起作用。如果我在y和n中輸入除單詞以外的任何內容，則會顯示以下錯誤。

Traceback (most recent call last): 
    File "C:\Users\Prateek\Desktop\dictionary.py", line 46, in <module> 
     in_dict() 
    File "C:\Users\Prateek\Desktop\dictionary.py", line 43, in in_dict 
     add_word() 
    File "C:\Users\Prateek\Desktop\dictionary.py", line 20, in add_word 
     ans() 
    File "C:\Users\Prateek\Desktop\dictionary.py", line 16, in ans 
     ans() 
TypeError: 'str' object is not callable

用'ans = raw_input（「Y/N」）覆蓋函數名稱' –
