Writing Python Like Rust

Re:Writing Python Like Rust by dsissitka on Wednesday June 28, 2023 @11:57PM (#36516146)

I was curious:

  SLOC    Directory       SLOC-by-Language (Sorted)
  232099  tests           python=232099
  102470  django          python=102470
  424     docs            python=424
  158     scripts         python=142,sh=16
  21      top_dir         python=21
  0       extras          (none)
  0       js_tests        (none)
  
  Totals grouped by language (dominant language first):
  python:      335156 (100.00%)
  sh:              16 (0.00%)

Wow, 2.3x for tests/src ratio. I remember some recommendation for Java to have around 0.9x ratio, otherwise too much tests maintenance.

Depends on the project of course, e.g. SQLite has an insane ratio.

Could also be that Java's typing already accounts for some part of what would need to be tests in Python code...

Exactly, that's what I meant. E.g.

    if very_rare_condition:
       raise MyRareException

Java wouldn't compile (no exception instantiation), but Python would work fine in production until the rare condition happened (but not captured above, as it's a class, not instance). Cases like that justify 100% tests coverage in Python, but not Java.
