無效的語法，而真正的statemtn

Question

這裏是我的腳本：

def makeithappen(): 
    word="" 
    while True: 
     try: 
      word=inputText() 
     except: 
      print("Something happened inputText") 
     else: 
      if len(word)>0: 
       break 
      elif word!=str: 
       break 

出於某種原因，但我得到一個無效的語法錯誤，我不知道爲什麼。

Answer 1

def makeithappen(): 
    word="" 
    while True: 
     try: 
      word=input() #is this supposed to be input()? 
     except: 
      print("Something happened inputText") 
     else: 
      if len(word)>0: 
       break 
      elif isinstance(word, basestring): #I never got the logic behind it 
       break 

我認爲這是你想要做的。如果輸入的文本有效（長度大於0）並且輸入類型不是str（對於python3，總是false），它將退出。

#!/usr/bin/python 
# -*- coding: utf-8 -*- 

def makeithappen(): 
    word="" 
    while True: 
     try: 
      word=raw_input("Go:") 
     except: 
      print("Something happened inputText") 
     else: 
      if len(word)>0: 
       print("Hello!!") 
      elif word!=str: 
       print("Bye!!") 
       break 
makeithappen()
