Empty strings are "falsy" (python 2 or python 3 reference), which means they are considered false in a Boolean context, so you can just do this:
if not myString:
This is the preferred way if you know that your variable is a string. If your variable could also be some other type then you should use:
if myString == "":
See the documentation on Truth Value Testing for other values that are false in Boolean contexts.

Both None and "" are falsy values so simply if not variable: will cover both those cases. This doesn't explicitly check for those values but if you're just checking for something not being set this is probably the way to go. More on reddit.com

July 6, 2021empty string returns True upon checking if its contained in a non empty string
Yes, empty strings are in any other string. Like the empty set is a subset of any other set. I feel like there’s probably many easier ways to do what you’re trying to do here (which seems to be looking for the string “di” within another string without case sensitivity?) but to minimize the change to your approach, if you want to initialize previous so it returns false without raising a type error, you could initialize it with a long string that can’t possibly be in the search string. After the first iteration it will be set by the loop code and won’t be empty again. More on reddit.com

From PEP 8, in the “Programming Recommendations” section:
For sequences, (strings, lists, tuples), use the fact that empty sequences are false.
So you should use:
if not some_string:
or:
if some_string:
Just to clarify, sequences are evaluated to False or True in a Boolean context if they are empty or not. They are not equal to False or True.

August 5, 2022 - There's a straightforward answer to this that takes advantage of the truth value of strings. In Python, any object can be tested for truth value, including strings. In this context, strings are considered truthy if they are non-empty, meaning they contain at least one character.

How to Check if a String is Empty or None in Python
June 5, 2023 - In both of these methods, the if statement will print "String is empty" if the string s is empty. The not operator in the second example negates the "truthiness" or "falsiness" of the string, making the code slightly more concise. This is a common Pythonic way to check for empty strings.

What are my options? Can I create somehow a class and check against that class?

How would I write such a class?

The “empty string” bit isn’t what’s tripping you up, your loop is hand-checking for a ‘d’ then an ‘i’. In "imagina." there’s never a ‘di’ sequence, so flag_di stays False and you should get 0. If you’re seeing 1, double-check that you’re resetting flag_di and previous properly when you hit the delimiter. As a shortcut, you could also do: words = texto.strip('.').split() answer = sum('di' in w.lower() for w in words) print(answer)
