1. Environmental preparation
1. When the library is missing, there will be a corresponding prompt in the black window. Execute the following command + package name to download and install
. 2. The idea used by the blogger here is directly downloaded by Alt+Enter. 3. The idea of
configuring the python environment can also refer to this Text: Python (including PyCharm and configuration) download and installation and simple use (Idea)
