It’s time to dig deeper into our work with numbers (including math) and strings.
First of all, it might be handy (especially as you learning), to have Python report the type of a variable or a literal value. For example:
C:\Users\terry>py
Python 3.7.4 (tags/v3.7.4:e09359112e, Jul 8 2019, 20:34:20) [MSC v.1916 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> type(199.9)
<class 'float'>
>>> type("Howdy!")
<class 'str'>
>>> type(10043)
<class 'int'>
>>> a = "This is cool!"
>>> type(a)
<class 'str'>
>>>
Division in Python comes in two variations:
/ carries out floating point division
// caries out integer (truncating) division
For example:
>>> 15 / 4 3.75 >>> 15 // 4 3
Many of the math precedence rules would make sense to us (those that took some math in school!) For example, multiplication wins over addition. But fortunately, Python supports the use of ( ) to indicate precedence. This keeps us from having to worry about default behaviors. Here is an example:
