Operators and expressions
Operators in Python are symbols that are used to perform operations on variables and values. Python supports a wide range of operators, including arithmetic, comparison, logical, and bitwise operators.
Arithmetic operators are used to perform mathematical operations on numerical values. These operators include addition (+), subtraction (-), multiplication (*), division (/), modulus (%), and exponentiation (**).
Comparison operators are used to compare values and return a Boolean value (True or False). These operators include equality (==), inequality (!=), greater than (>), less than (<), greater than or equal to (>=), and less than or equal to (<=).
Logical operators are used to combine Boolean expressions and return a Boolean value. These operators include and, or, and not.
Bitwise operators are used to perform bitwise operations on integers. These operators include and (&), or (|), exclusive or (^), left shift (<<), and right shift (>>).
Expressions in Python are combinations of values, variables, and operators that are evaluated to produce a result. For example, 2 + 3 is an expression that evaluates to 5. Expressions can be simple, such as a single value, or complex, such as a combination of multiple operators and values.
Python also supports expressions with variables, which are used to store and manipulate data. Variables can be assigned values using the assignment operator (=). For example, x = 5 assigns the value 5 to the variable x.
Overall, operators and expressions are important concepts in Python for performing operations and manipulating data. Understanding these concepts is essential for building Python programs that perform complex computations and data manipulations.
