STINNER Victor <vstin...@python.org> added the comment:
Example of sys.orig_argv usage to re-execute the Python process with different
options:
---
import sys
import os
if not sys.flags.utf8_mode:
# Force UTF-8 mode
argv = sys.orig_argv.copy()
argv[1:1] = ["-X", "utf8"]
print(f"Re-execute to force UTF-8 mode! argv={argv}")
os.execv(argv[0], argv)
print(f"Everybody loves UTF-8! utf8_mode={sys.flags.utf8_mode}")
---
Example coming from discussions on the PEP 597 :-)
Output:
---
$ ./python force_utf8_mode.py
Re-execute to force UTF-8 mode! argv=['./python', '-X', 'utf8',
'force_utf8_mode.py']
Everybody loves UTF-8! utf8_mode=1
