For example, if you have a variable that you want to 'raw string': Note: Use string-escape for python 2.x and older versions, I was searching for a similar solution and found the solution via: A Unicode object takes more memory space. In raw strings, escape sequences are not treated specially. Raw strings are not a different kind of string. They are a different way of describing a string in your source code. Once the string is created, it here is the code: And then to convert it back to a regular string do this. Raw strings are particularly useful when working with regular expressions, as they allow you to specify patterns that may contain backslashes without having to escape them.

Basically, the difference between raw_input and input is that the return type of raw_input is always string, while the return type of input need not be string only. Finally, we summarised the different ways of string representation in Numpy and Pandas, and special care should be taken when instantiating Numpy or Pandas objects with string because the behaviors will be drastically different than primitive Python strings. The rule that defines the encoding process is called encoding schema, commonly used ones include ASCII, UTF-8, etc. We discussed the use of the repr() function to achieve the same.
