Python格式化輸出

從C語言轉過來學習python的人，總是習慣於在格式化輸出後面加上”,”. 導致在編譯時間出錯。

#!/usr/bin/pythonclass Person:    def speak(self):        print "I can say anything!"    def walk(self,distance):        print "I can walk %d", %distancepeople = Person()people.speak()people.walk(30)

 

$ python class.py

  File "class.py", line 8

    print "I can walk %d", %distance

                           ^

SyntaxError: invalid syntax

 

尋找了半天，原來是多加了一個”,”導致。

將print "I can walk %d", %distance 中的，去掉就OK了.
