The program must contain a requirements.txt file that records all dependent packages and their exact version numbers. If you want to regenerate the virtual environment on another computer.Pip can automatically generate this file using the following

Through this period of pre-research, we found that the Python language supports few and extremely immature WSS frameworks. Now we can understand soappy, pygridware, and NDG security. Of course, these frameworks also depend on some well-known
