This article mainly introduces how to achieve python script in ubuntu can be run directly, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

Let's take that translation program as an example. Last time, I told you about the packaging of applications under windows. This time, I will tell you that python files can be executed on their own under linux, so there is no need for python xxx.py.

Very simply, add the following sentence to the top of the python source file!

#! / usr/bin/python3

/ usr/bin/python3 is the directory where the python3 interpreter is located under ubuntu. You can check it with which python3.

Then add executable permissions to the python script after executing chmod + x. / xxx.py

For example, here I am

Sudo chmod + x. / translate.py

Finally run. / translate.py

And then. Wrong report

-bash:. / translate.py: / usr/bin/ python 3 ^ M: interpreter error: there is no such file or directory

Why?

This is the source code I wrote under win7, which was later transmitted to ubuntu with winscp, so it caused a problem. The code written under dos, taken to linux, is incompatible.

Solution:

Sudo vim translate.py:set ff=unix

And then execute. / translate.py

OK runs perfectly, but if you take a closer look, it doesn't seem perfect, because every time you have to change to the directory where the file is located to run. In order to use the program more effectively, we can connect translate.py to / usr/bin, or / usr/local/bin, and so on, in a directory configured with system environment variables.

Sudo ln-s / xxxx/xxxx/xxxx/translate.py / usr/local/bin/dict

/ xxxx/xxxx/xxxx/, which is the absolute path where translate.py is located

/ usr/local/bin/dict,dict is renamed after translate.py soft connection

Running effect

OK, will there be a ready-made translation program in my ubuntu system in the future? Isn't it beautiful!
