Day02:python Interpreter

1, #!/usr/bin/python: When executing the script, call/usr/bin under the Python interpreter, its path is fixed;
2, #!/usr/bin/env python: is to prevent users from not loading Python in the default/usr/bin path, but instead of customizing the settings path. When the script is executed, the installation path of Python is first looked up in the env settings, and the Python installation path is found by invoking the interpreter program under Environment settings.
3, the default encoding format in Python is ASCII format, when reading Chinese will error. Just add #-- Coding:utf-8--or #coding =utf-8 to the beginning of the file to display the Chinese normally.
