What type of language is Python:

Compiled language, the code before the implementation of the plaintext, first turn to binary, in the execution, the process is called compiling; (C,c++,go)

Features: High operating efficiency; Depending on the build platform, the Linux operating system interacts with the CPU with Windows not exactly the same (e.g. Linux:print_to_console,windos:print_to_screen);

Cons: No cross-platform, low development efficiency
