Python is a computer language that can be used for many things like creating websites, studying data, and building smart machines. Strings are an important way of storing and working with text in Python. This piece of writing will cover the basics of strings, including their definition, how they can be made, and a few typical actions you can do with them. What are Strings in Python?

Example Using the ` strip()` method, you can eliminate any whitespace located at the start or end of a string : x =  " Hello, World! " print (x.strip())  # returns "Hello, World!" Replace String Example With the ` replace() ` method, you can substitute one string with an...
