Numeric literals are used for representing numeric values in the source code. They can be of three types - integers, float point numbers and imaginary numbers.

Integer literals are numbers without any fractional component.

Some valid underscore usages are - `10_00_00_000`, `0b_1110_0101`, `0x23_123`.

Floating point literals are real numbers present in the source code. They contain fractional component and/or exponential component.

For example, `3.4E2` is equivalent to `3.4 x 10^2` or `340.0`, whereas `3.4e-2` is equivalent to `3.4 x 10^-2` or `.034`.

To specify complex numbers and perform complex number mathematics, Python supports imaginary literals which are given by real or integer number followed by the letter `j` or `J` which represents the unit imaginary number.

Numeric data types are used for storing the following types of numbers:

Objects holding integer numbers like `-1, 0, 200` are of `int` data type.

Objects holding real or floating point numbers like `-1.1, 3e2, 20.0` are of `float` data type.

Objects storing complex numbers like `2 + 1j, -3j, -1 + 2J` are of type `complex`.

Each complex number has two parts, the real part which is a numeric integer or floating point literal, and the imaginary part which is an imaginary literal.

The boolean data type (`bool`) is a subtype of `int`. It stores the evaluated value of expressions represented as keywords - `True` (integer value `1`) and `False` (integer value `0`).

An ordered collection of items where each item can be accessed using an integer index is known as a sequence. The following three sequence data types are available in Python:

A string (`str` data type) is a sequence of zero or more unicode characters enclosed within a pair of single (`'`) or double (`"`) quotes.

Some example strings are - `"42", 'hello', "python"`.

A `list` is sequence of items of same or different data types which are enclosed within brackets - `[ ]`.

Some example lists are - `[1, 2, 3]`, `['abc', 23, 3.14]`, `['edpunk', 'python']`.

A `tuple` is an immutable sequence of items of same or different data types which are enclosed within parentheses - `( )`.
