This is basically the same as x = 42 print(x) print(x) print(x) A variables value only changes when you assign it: x = 42 print(x) x = 45 print(x) If you want a new random value, you need to call the function again: l = [1, 2, 3, 4, 5] x = random.choice(l) print(x) x … Read more
Assuming you don’t care what the file names are, you could write each batch of messages to a new temp file, thus: import tempfile texts = some_function_grabbing_text() while texts: with tempfile.TemporaryFile() as fp: fp.write(texts) texts = some_function_grabbing_text() solved How to save data in multiple files on python
Why not use a dictionary for that? This way you could add and remove values in/from your dictionary just as you wanted. my_dict = { ‘var1’: 0, ‘var2’: 0, … } You can delete by doing my_dict.pop(‘var1’) if you need the value back or del my_dict[‘var1’] otherwise and add items with my_dict[‘var3’] = 0. 2 … Read more
