The in operator in Python is the most straightforward and idiomatic way to check if an element exists in a list. This operator performs a membership test, returning True if the specified element is present in the list and False otherwise. Its simplicity and readability make it the go-to ...
An iterable object is any object that can be iterated over using aforloop. Some examples of iterable objects in Python are strings, lists, and tuples. When developing with Python, you may get a variable or custom object, but you don’t know if it’s iterable or not. Knowing if a giv...

Here, we have a list and a tuple and we need to check if there exists any one element which is common in both list and tuple in Python.
The Python len() is used to get the total number of characters present in the string and check if the length of the string is 0 to identify the string is empty. Actually, the len() function returns the length of an object. The object can be a string, a list, a tuple, or other ...
Check if a list has duplicate Elements using Sets We know that sets in Python contain only unique elements. We can use this property of sets to check if a list has duplicate elements or not. For this, we will create a set from the elements of the list. After that, we will check the...
But theMatchobject is a powerful container of information and, like you’ve seen earlier, you can pick out just the information that you need: Python >>>formatchinre.finditer(r"(secret)[\.,]",file_content):...print(match.group(1))...secretsecret ...
Using len() Function to Check if a String is Empty or Whitespace in Python The len() function is used to find the length of an iterable object such as a list, string, tuple, etc. It takes the iterable object as its input argument and returns the length of the iterable object. To c...
2. What is None in Python? In Python, None is a special constant that denotes the absence of value or a null value. It is object of its own datatype, the NoneType. 3. Using the is Operator The is operator is the most straightforward and recommended method to check if a variable is...
