Python是新的流行语言,特别是在金融行业,我开始学习它。我从Python网站下载了它- Python版本3.5.2 -它成功地安装了...在我的应用程序文件夹中。为了让你更多地了解我自己,我在法国上过一所IT工程学校,所以我有IT文化,但我从来没有黑客的灵魂,所以有些事情可能比其他事情更困难。
开始在Python IDE上编码,然后我创建了一个可执行的python文件,当我试图执行它时……错误!!
这是我执行文件时得到的结果(bissextile.py - file应该要求用户输入年份,并告诉他今年是否为双六位数):

所以,我在这里看到了两个问题: 1)我的文件不工作... 2) shell使用的不是Python 3.5,而是Python 2.7,这是我需要帮助的问题。
在互联网上做了很多研究,我正要按照那个教程去做:https://wolfpaulus.com/journal/mac/installing_python_osx/comment-page-3/#comment-101285 ...and将要从我的mac中删除一些系统文件:)它不让我do...decided我真的不知道我在做什么,我应该在互联网上多挖掘一点。根据记录,下面是我在/System/Library/Frameworks/python.framework/Versions/中拥有的内容:
所以我找到了一个叫做" Homebrew“的东西,它应该为你安装Python,我遵循了这个很棒的教程:http://blog.manbolo.com/2014/09/27/use-python-effectively-on-os-x#p1要求Homebrew安装Python3.5而不是Python2.7(步骤完全相同),我显然是这么做的。
所以我做了教程中建议的验证,以确保我使用的是正确的Python版本,但当我询问shell时,我仍然得到了Python2.7。我检查了我的/etc/path文件,如下所示:
/usr/local/bin
/usr/bin
/bin
/usr/bin
/bin
/usr/local/bin是文件中的第一个二进制文件,我检查了它包含Python3.5的文件夹。但是不管文件的第一行是什么: MacBook-Pro-de-Tebah:~ tebahsaboun /usr/bin/python和:

我不能把到目前为止我研究过的所有链接(特别是堆栈溢出的文章;顺便说一句)放在一起,因为我没有足够的“声誉”,但我做了很多研究,似乎没有文章回应我的问题。我不明白哪里出了问题。

使用python3 my_script.py
或添加shebang #!/urs/bin/python3
从命令行运行程序
