Python pipes Module
Note: The pipes module is Unix-only and has been deprecated , use subprocess instead.
Example
Create a simple pipeline (uppercase) and write to a file (Unix only):
# This only works on Unix systems and older Python versions (< 3.13)
import pipes
tmpl = pipes.Template()
tmpl.append('tr a-z A-Z', '--')
with tmpl.open('out.txt', 'w') as f:
f.write('hello')
Definition and Usage
The pipes module builds shell-style pipelines using a small Template helper.
Prefer the subprocess module for new code. pipes was platform-specific and limited.
