Tương đương của Python là "perl -V"

Question

Kết quả được tạo ra bằng cách chạy perl -V được đóng gói với thông tin hữu ích (xem ví dụ bên dưới). Có điều gì giống như nó cho Python?

Ví dụ đầu ra:

% perl -V

Không nên nhầm lẫn với ít nhiều thông tin perl -v:

Answer 1

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

Answer 2

Mặc dù đây là vô cùng hackish, không thực tế, và không chi tiết như perl -V, đây là một lớp lót có thể nhận được thông tin phong nha về môi trường.

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

Vì đây không phải là của mình điển hình dễ nhớ lệnh, bạn có thể tiết kiệm dòng này vào thư mục Lib Python như sys_info.py và sau đó bạn chỉ có thể chạy:

python -m sys_info
