 ## Strings
 
 Strings are sequences of characters. Your name can be considered as a string. To create a string, put the sequence of characters inside quotes. Python does not care if they are single quotes or double quotes and so `'pyjaipur'` and  `"pyjaipur"` are the same value. You can read more about python string [in the python docs](https://docs.python.org/3/tutorial/introduction.html#strings).
