"Python applications will often use packages and modules that don't come as "
"part of the standard library. Applications will sometimes need a specific "
"version of a library, because the application may require that a particular "
"bug has been fixed or the application may be written using an obsolete "
"version of the library's interface."

"This means it may not be possible for one Python installation to meet the "
"requirements of every application. If application A needs version 1.0 of a "
"particular module but application B needs version 2.0, then the requirements "
"are in conflict and installing either version 1.0 or 2.0 will leave one "

"Different applications can then use different virtual environments. To "

"application B requires a library be upgraded to version 3.0, this will not "
