Reply content:These three are very handy for Python project deployment. 1. Virtualenv is used to create a virtual Python environment, a project-specific Python environment. It is very useful to use virtualenv to keep a clean environment. 2. Pip is used to solve the project dependency problem. Write all dependent third-party libraries of the project in one Requirements.txt and batch install with PIP. Typically used in conjunction with VIRTUALENV, all packages are installed in the VIRTUALENV envir
