为什么python 2.7“代理”像python 3？
[英]why is python 2.7 "Acting" like python 3?
问题描述
i just started learning Python (w no prior programing experience whatsoever) so i was asked to get TextWrangler and type: print "hello world" (of course) and then RUN it through Terminal app on Mac.
我刚开始学习 Python（之前没有任何编程经验），所以我被要求获取 TextWrangler 并输入： print "hello world" （当然），然后通过 Mac 上的终端应用程序运行它。 i was also asked to use Python 2.7 NOT Python 3!!!我还被要求使用 Python 2.7 而不是 Python 3！！！ but when i wrote the line as i was told to on the video print "Hello World" the Terminal app showed a syntax err!但是当我按照视频print "Hello World"的指示写下这行时，终端应用程序显示语法错误！ when i wrote the line print ("hello world") then it went through with no problem and was executed by Terminal.当我写行print ("hello world")它毫无问题地通过并由终端执行。 why is my python 2.7 acting like python 3, if i can put it that way?如果我可以这样说，为什么我的 python 2.7 表现得像 python 3？ When i type python --version in terminal it shows that i run 2.7 version.当我在终端中输入python --version ，它显示我运行的是 2.7 版本。 Thanks.谢谢。

您可以在终端中通过冲突版本明确请求 python 2 shell，如下所示：
alias python='python2'
