Change the mirror source in Pycharm
Mirror website is to place an identical website on several servers, each with its own URL, and these servers are mirror websites for each other. It is not much different from the master station, or it can be regarded as a backup measure for the master station. The advantage of having a mirrored website is: if you can't make normal access to the main website (such as a server dies or an accident), you can still browse normally through other servers. Relatively speaking, the main site is slightly better than the mirror site in terms of speed and other aspects.
Simply put, downloading files from mirror sources will greatly speed up the download speed and save time and effort.
