The purpose of this package is to provide a simple way to launch processes in Python but in the same shell. Only one shell is allocated and all the processes are launched in order. There is no need to allocate a different shell on each execution, and therefore it benefits from faster execution and a smaller memory footprint.
Installation via pip:
pip install sharedshell
Using it:
from sharedshell import SharedShell with SharedShell() as shell: print(shell.run('echo 1').stdout) print(shell.run('echo 2').stdout) print(shell.run('echo 3').stdout)
Output:
1 2 3
