In this article, we’re going to talk about what
shebang means in Python and how you can use it in a command. We’ve included an example program to help you understand the concept of Python
shebang character sequence is a special character sequence in a script file denoted by
#!. It helps in specifying the type of program that should be called to run the entire script file. The
shebang character sequence is always used in the first line of any file.
The statement that mentions the program’s path is made by using the
shebang character first and then the path of the interpreter program.
shebang in Python
For all the scripts that are to be executed in Python3, use the following command in the command line:
python2 if the script is only compatible with Python 2.7 version.
If the script is compatible with both Python 2 and Python 3, the following command can also be used:
This code is also understandable on Windows Python Launcher.
The program above is preferred when writing a
shebang command in a virtual environment like
pyenv. Previously known as
pyenv is a simple Python version management tool that helps manage the Python version, install the latest Python versions, and create a virtual Python environment.
In most cases, a Python interpreter is installed at
/bin/python. In these two cases, the
shebang statement will fail if the following command is used:
In conclusion, the
shebang command is just a way of denoting that the following script is executable. Therefore, the result of any python script will never be affected if the
shebang command is executed, whether it is mentioned or not.
