Python'un "perl -V" eşdeğeri nedir?

Question

perl -V çalıştırarak üretilen çıktı, yararlı bilgilerle paketlenmiştir (aşağıdaki örneğe bakın). Python için böyle bir şey var mı?

Answer 1

python -c 'import sysconfig, pprint; pprint.pprint(sysconfig.get_config_vars())' 

Answer 2

bu inanılmaz, hackish pratik ve olduğunca detaylı olmasa da perl -V, bu çevre hakkında iyi bilgi alabilen tek liner. Bu yana

python -c "import platform as p;exec('for x in vars(p):\n try:\n print ({x:vars(p)[x]()})\n except:\n pass')" 

değil senin tipik kolay hatırlamak komutu, sen sys_info.py olarak Python'un Lib dizinine bu çizgiyi kurtarabilecek sonra sadece çalıştırabilir:

python -m sys_info
