How to make this script more faster i just complet coding but i need some tricks to make it fast

[keuninkske]

hello,

never compared the speed, but it would be nicer to read them all into a list

then you can sort the list
sorting python lists
and you can count what is in this list
you can count how many gmails there are in that one list

now that i am thinking about it, you do not even need to sort them

outputting them afterwards from the list should also be faster than outputting one by one to your file system
