Type

The characteristic of the numeric value that determines its kind, range, and application

Integers

Numbers devoid of the fractional part

Floating Points

Numbers that contain or can contain the fractional part

Underscores

What Python does allow, though, is the use of this in numeric literals

Negative numbers

Written by adding a minus (-)

Octal value

Treated as this if an integer number is preceded by an 0O or 0o prefix (zero-o)

Hexadecimal value

Treated as this if it is preceded by the prefix 0X or 0x (zero-x)

Point (.)

Essentially makes a number a float

E/e

Represents exponents incorporated into a number string

Exponent

The value after E has to be an integer, while the base (value in front of the E) may be an integer

Strings

These are used when processing texts and not numbers

Escape character

Played by the backslash ()

Apostrophe (')

The second solution is to use this instead of a quote

Boolean value

Each time Python is asked if one number is greater than another, it always results in the creation of some specific data

Boolean algebra

A part of algebra that makes use of only two distinct values True and False, denoted as 1 and 0

Expression

A combination of values, variables, operators, and function calls that result in a computed value.

Expression Evaluation

It is evaluated by Python to produce a value.

Arithmetic Expressions

These involve mathematical operations such as addition (+), subtraction (-), multiplication (*), division (/), and exponentiation ().

Relational Expressions (or Comparison Expressions)

These evaluate to True or False using comparison operators.

Logical Expressions (or Boolean Expressions)

These use logical operators (and, or, not) to combine Boolean values.

Bitwise Expressions

These manipulate bits directly using bitwise operators (&, |, ^, ~, <<, >>).

Assignment Statement

Assigns a value to a variable using the = operator.

Assignment Operator (=) Structure

The left-hand side is the variable name, and the right-hand side is the value to be stored.

Augmented Assignment Operators

Provides a concise syntax to update variable values by combining an arithmetic operation with an assignment operator, reducing redundancy in code.
