Introduction
This chapter will expand our understanding of programming by introducing types and literals. All objects in Python have a type, and literals are fixed values of a given type. For example, the literal 1 is an integer and is of type int (short for 鈥渋nteger鈥�). Python has many different types.
Learning objectives
- You will learn about many commonly used types in Python.
- You will understand why we have different types.
- You will be able to write literals of various types.
- You will learn different ways to write string literals which include various quotation marks within them.
- You will learn about representation error as it applies to numeric types (especially floating-point values).
Terms introduced
- dynamic typing
- escape sequence
- empty string, empty tuple, and empty list

- static typing
- 鈥渟trong鈥� vs 鈥渨eak鈥� typing
- type (including
int,float,str,list,tuple,dict, etc.) - type inference
