Eclipse Pydev：未定义的变量：打印输入

Question

所以，我正在使用带有 Pydev 版本 7.2.1.201904261721 的 eclipse Oxygen.3a Release (4.7.3a,20180405-1200)。我正在通过 pdf 学习 python，并且在一次重新启动时，我的代码被“未定义的变量：打印”垃圾邮件。但是，当我解释并运行代码时，一切正常。为什么会这样？我该如何解决？ 这是我的代码（在单个项目中名为 rock1.py）：

import random
choices= ["rock paper sissers "]
player=input("do you want to be rock paper or sissors  (or quit?)")
computer= random.choice("choices")
while player!=("quit"):
    print("you choose,"+player+",computers choose"+computer+".")
if player== computer:
    print("it's a tie")
else:
    print("computer wins")    
if player == ("rock"):
        if computer == ("sissors"):
            print("youwin")
elif player == ("sissors"):
        if computer==("paper" ):
            print("you win")
        elif player==("paper"):
            if computer== ("rock"):
                print("youwin")
            else:
                print("computer win")
        else:
                print ("i think there is a kind of error")
                print("i think there is a kind of error")        

错误（直接取自 eclipse 问题选项卡）：

Answer 1

这通常发生在 PyDev 无法与它为获取内置令牌而生成的 shell 通信时（Python 3 上的 print 就是这种情况）。
