Python not ignoring empty items in list -


i have code print strings text file, need python ignore every empty items, doesn't print empty lines.
wrote code, simple, should trick:

lastreadcategories = open('c:/digitallibrary/' + connecteduser + '/lastreadcategories.txt', 'w') category in lastreadcategorieslist:     if category.split(",")[0] not "" , category not none:         lastreadcategories.write(category + '\n')         print(category)     else: print("/" + category + "/") lastreadcategories.close()

i can see no problem it, yet, python keeps printing empty items file. categories written in notation: "category,timesread", that's why ask python see if first string before comma not empty. see if whole item not empty (is not none). in theory guess should work, right?
p.s.: i've tried asking if check if 'category' not "" , not " ", still, same result.

rstrip() category before writing file

lastreadcategories = open('c:/digitallibrary/' + connecteduser +'/lastreadcategories.txt', 'w') category in lastreadcategorieslist: if category.split(",")[0] not "" , category not none:     lastreadcategories.write(category.rstrip() + '\n')     print(category.rstrip()) else: print("/" + category + "/") lastreadcategories.close()

i able test sample list provided (without writing file):

lastreadcategorieslist =  ['a,52', 'b,1\n', 'c,50', ',3'] category in lastreadcategorieslist: if category.split(",")[0] not "" , category not none:     print(category.rstrip()) else: print("/" + category + "/")  >>> ================================ restart ================================ >>>  a,52 b,1 c,50 /,3/ >>>
