python - 简单 if 语句的 Python 语法错误

Question

我的 if 语句出现语法错误：

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应改为if. 观察小写i。

>>> If True:

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


True
