Python has the characteristics of open source, cross platform, interpretive, interactive and so on, which is worth learning.
Python's design philosophy: elegant, clear, simple. Advocate one way, preferably only one way to do one thing.
The code should be written in accordance with the standard, which is conducive to communication and understanding.
Each language has its own unique ideas. Beginners need to change their thinking, practice and accumulate.
