Given a string representing one Unicode character, return an integer representing the Unicode code point of that character.
15+
The pow() function returns the power of a number.It takes two or three arguments:
16+
pow(base, exp): Returns base raised to the power of exp (base ** exp).
17+
pow(base, exp, mod): Returns (base ** exp) % mod (for modular arithmetic).
18+
Result is computed more efficiently than base ** exp % mod, if mod arg is present.

A decorator can also be defined as a class instead of a method. This is useful for maintaining and updating a state, such as in the following example, where we count the number of calls made to a method:
109+
To decorate a class method, you must define the decorator within the class. When
110+
only the implicit argument`self` is passed to the method, without any explicit
111+
additional arguments, you must make a separate decorator for only those methods
112+
without any additional arguments. An example of this, shown below, is when you
113+
want to catch and print exceptions in a certain way.
