# pycstats

Statistics on Python bytecode

Requirements:

- CPython 3.9+

- pip

- [regex](https://pypi.org/project/regex/)

- bash

- curl

- jq

- unzip

- find

Tested on GNU/Linux and probably won't work anywhere else.

```bash

$ # download all packages and compile bytecode

$ ./download.sh

$ # analyse pyc files with regex-ish

$ # (e.g. look for LOAD_CONST followed by anything other than RETURN_VALUE)

$ find . -name '*.pyc' | ./analyse_regex.py LOAD_CONST '(?!' RETURN_VALUE ')'

...............

245

$ # scan all length-3 opcode sequences

$ find . -name '*.pyc' | ./analyse_sequences.py 3

208838 LOAD_CONST LOAD_CONST LOAD_CONST

165043 LOAD_CONST LOAD_CONST MAKE_FUNCTION

107435 STORE_NAME LOAD_CONST LOAD_CONST

103254 LOAD_CONST MAKE_FUNCTION STORE_NAME

81826 MAKE_FUNCTION STORE_NAME LOAD_CONST

[...]

```

To use with the Python standard library:

```bash

$ sudo python -m compileall

$ find . /usr/lib/python3.9/ -name '*.pyc' | ./analyse_[...]
