We can say Python datatypes are collections of data items that help us classify or categorise data. Every value in Python has a data type, and every data type is a class that stores a variable (object).
In a programming language like Python, there are mainly 4 data types:
- String – It is a collection of Unicode characters (letters, numbers and symbols) that we see on a keyboard.
- Numerical – These data types store numerical values like integers, floating-point numbers and complex numbers.
- Boolean – A boolean is used when we wish to restrict data to True/False or yes/no options.
- Sequence types – These help us store ordered collection of similar or different data types. List, string, and tuples are the types of sequence data types.
Apart from the four main data types mentioned above, sets and dictionaries are data types that are unordered and non-indexed. We cannot change any item value after we define it in a dictionary or set. We also cannot access an item using an index value.
