Number data types store numeric values. They are an immutable data type, which means that changing the value of a number data type results in a newly allocated object.
Number objects are produced when you assign a value to them.
Python holds four special numerical types:
• int (signed integers)
• long (long integers [can also be represented in octal and hexadecimal])
• float (floating point real values)
• complex (complex numbers)
• Python agrees to you to use a lowercase L with long, but it is optional that you use only an uppercase L to keep away from confusion with the number 1. Python shows long integers with an uppercase L.
• A complex number consists of an organized pair of real floating point numbers denoted by a + bj, where a is the actual part and b is the invented part of the complex number.
