Spyder is an application where you can edit and run your Python scripts. As part of Anaconda, there are a large number of. A Python script can also be started like any other script under Linux, e.g. Bash scripts. Two steps are necessary for this purpose: the shebang line #!/usr/bin/env python3 has to be added as the first line of your Python code file

Running it: $ sh -s <script.sh TESTPRINT. What happens here is that the script is being run by sh -s. The -s option to sh (and to bash) tells the shell to execute the shell script arriving over the standard input stream. The script then starts python -, which tells Python to run whatever comes in over the standard input stream 0. This question is answered here: Running Python File in Terminal. If none of these work: You can save your code as a script in gedit with a .py file extension ie. exampleFile.py. But on the first line add #!/usr/bin/python and save. Make the script executable by entering. chmod +x exampleFile.py The coder needs less time and effort if any good editor is used for writing the code.
