Question:

How do I migrate from Python 2.7 to Python 2.8 ?

Answer:

Migrating from Python 2.7 to Python 3 is a crucial step, especially since Python 2 reached its official end-of-life at the start of 2020. Here's a guide to help you transition your code:

1. Assess Your Codebase:
   • Focus on supporting Python 2.7 initially.

input = Path(sys.argv[1])
for line in input.read_text().splitlines():
    # Ignore date of the modification
    if line.startswith('"PO-Revision-Date:'):
        continue
