It is easy getting a Python list installed modules on the system. As we keep coding in Python, we install many packages. List installed packages (with the default column formatting).The main strength of the Python is, the wide range of external libraries are available. Links to VCS project URLs are not supported. If a local path or file:// URL that’s a directory, then look for archives in the directory listing. If a URL or path to an html file, then parse for links to archives such as sdist (.tar.gz) or wheel (.whl) files. Ignore package index (only looking at -find-links URLs instead). Should follow the same rules as -index-url. extra-index-url #Įxtra URLs of package indexes to use in addition to -index-url. This should point to a repository compliant with PEP 503 (the simple repository API) or a local directory laid out in the same format. exclude #Įxclude specified package from the outputīase URL of the Python Package Index (default ). exclude-editable #Įxclude editable package from output.
