一個簡單的if語句

Question

我在if語句出現語法錯誤Python語法錯誤：

print "Welcome to the English to Pig Latin translator!" 

original = raw_input("Please enter a word to be translated: ") 
word_length = len(original) 

def length_check(): 
    If (word_length) > 0 : <-- This colon brings up the following error: 
     return original 


File "python", line 7 
    If (word_length) > 0 : 
         ^
SyntaxError: invalid syntax 

Answer 1

If應改爲if。觀察小寫字母i。

>>> If True: 

SyntaxError: invalid syntax 
>>> if True: 
     print True 


True
