Strings are Arrays
Like many other popular programming languages, strings in Python are arrays of bytes representing unicode characters.

However, Python does not have a character data type, a single character is simply a string with a length of 1.

Square brackets can be used to access elements of the string.

Looping Through a String
Since strings are arrays, we can loop through the characters in a string, with a for loop.

String Length
To get the length of a string, use the len() function.

Check String
To check if a certain phrase or character is present in a string, we can use the keyword in.

Check if NOT
