PyQt5: How do you set the user input of a line edit to a specific variable?

[Denni]

Okay @buran first off I do stand corrected but only partially -- for importing PyQt import QtWidgets does not import the same thing as from PyQt.QtWidgets import QApplication, etc... because in the latter you have a single reference to a single method and this denotes exactly what you are using within that library within your program. This in turn makes your code more direct, less confusing and less verbose. And again not being specific is being lazy and lazy coding is always bad coding.

On the other hand -- yes the only difference between the two statements is what name is bound; import QtWidgets binds the name QtWidgets to the entire module (so QtWidgets -> QtWidgets.modules['QtWidgets']), while from QtWidgets import QApplication binds a different name, QApplication, pointing straight at the attribute contained inside of the module (so QApplication -> QtWidgets.modules['QtWidgets'].QApplication). The rest of the QtWidgets module is still there, whether you use anything else from the module or not.

Next my statement about super( ) is not arguable but go ahead and make that false claim just know that I fully researched super( ) before I made that statement -- all the pros/cons that I could find (quite numerable btw). So I am confident that I do know what it does and does not do. On the flip-side however I am guessing you do not even know why it was initially created -- aka the rare and specific issue it was created to handle -- nor are you probably aware of the issues that it creates when you do use it otherwise you would not have made your basically false claim
