How to execute python file in linux
提问by
I am using linux mint, and to run a python file I have to type in the terminal: python [file path], so is there way to make the file executable, and make it run the pythoncommand automatically when I doublr click it?
我正在使用 linux mint，要运行一个 python 文件，我必须在终端中输入：python [file path]，那么有没有办法让文件可执行，并让它python在我双击时自动运行命令？
And since I stopped dealing with windows ages ago, I wonder if the .py files there are also automatically executable or do I need some steps.
而且由于我很久以前就停止处理 Windows 了，我想知道那里的 .py 文件是否也可以自动执行，或者我是否需要一些步骤。
Thanks
谢谢

You have to add a shebang. A shebang is the first line of the file. Its what the system is looking for in order to execute a file.
你必须添加一个shebang。shebang 是文件的第一行。它是系统为了执行文件而寻找的。
It should look like that :
它应该是这样的：
#!/usr/bin/env python
or the real path
或真正的道路
#!/usr/bin/python
You should also check the file have the right to be execute. chmod +x file.py
您还应该检查文件是否具有执行权限。 chmod +x file.py
As Fabian said, take a look to Wikipedia : Wikipedia - Shebang (en)
正如 Fabian 所说，看看维基百科：维基百科 - Shebang (en)

yes there is. add
就在这里。添加
#!/usr/bin/env python
#!/usr/bin/env python
to the beginning of the file and do
到文件的开头并执行
chmod u+rx <file>
chmod u+rx <file>
assuming your user owns the file, otherwise maybe adjust the group or world permissions.
假设您的用户拥有该文件，否则可能会调整组或世界权限。
.py files under windows are associated with python as the program to run when opening them just like MS word is run when opening a .docx for example.
Windows 下的 .py 文件与 python 相关联，作为打开它们时运行的程序，就像打开 .docx 时运行 MS word 一样。

Add to top of the code,
添加到代码顶部，
#!/usr/bin/python
Then, run the following command on the terminal,
然后，在终端上运行以下命令，
chmod +x yourScriptFile
回答by NlightNFotis
I suggest that you add
我建议你添加
#!/usr/bin/env python
instead of #!/usr/bin/pythonat the top of the file. The reason for this is that the python installation may be in different folders in different distros or different computers. By using envyou make sure that the system finds python and delegates the script's execution to it.
而不是#!/usr/bin/python在文件的顶部。这样做的原因是python安装可能在不同发行版或不同计算机的不同文件夹中。通过使用，env您可以确保系统找到 python 并将脚本的执行委托给它。
As said before to make the script executable, something like:
如前所述，使脚本可执行，例如：
chmod u+x name_of_script.py
should do.
应该做。

1.save your file name as hey.py with the below given hello world script
1.使用下面给出的hello world脚本将您的文件名保存为hey.py
#! /usr/bin/python
print('Hello, world!')
2.open the terminal in that directory
2.在那个目录下打开终端
$ python hey.py
or if you are using python3 then
或者如果你使用的是 python3 那么
$ python3 hey.py
回答by 100RaBH
If you have python 3 installed then add this line to the top of the file:
如果您安装了 python 3，则将此行添加到文件顶部：
#!/usr/bin/env python3
You should also check the file have the right to be execute. chmod +x file.py
您还应该检查文件是否具有执行权限。chmod +x 文件.py
