Check for a String in a List of Strings in Python Sort List of Strings in Python Sort List of Strings According to the Length of Strings Conclusion Lists are one of the most used data structures in Python. In this article, we will discuss how to perform different operations on a list of...
In this code block, we first define a listmy_listcontaining three strings: “apple”, “banana”, and “cherry”. Then, we use theinoperator to check if “banana” is present inmy_list. If it is, the code inside theifstatement is executed, printing “Found!” to the console. 2. U...
Slicing won’t be useful for this, as strings areimmutabledata types, in terms of Python, which means that they can’t be modified. What we can do is create a new string based on the old one: We’re not changing the underlying string that was assigned to it before. We’re assigning...
In this example, we loop through each string in the list using a for loop. For each string, we use the in operator to check if the substring is present. If we find a match, we return True, indicating that the substring is present in at least one string. If no match is found ...

There are six whitespace characters in python namely space “”, tab“\t”, newline “\n”, vertical tab ”\v”, carriage return “\r”, and “\f” feed. We can use a list of these whitespace characters and a for loop to check if a string is empty or whitespace in python. For...
