Operators in Python
This article we explores about the operators that Python currently supports. You’ll also learn the basics of how to use these operators to build expressions.
In Python, operators are essential components used to perform computations. They consist of symbols, symbol combinations, or keywords. By combining these operators with objects, you create expressions that execute computations. These operators serve as the fundamental elements for manipulating data in Python, making a solid grasp of their functionality crucial for programmers.
In this tutorial, you’ll learn about the operators that Python currently supports. You’ll also learn the basics of how to use these operators to build expressions.
Introduction to Using Operators in Python
Python is a high-level programming language that is widely used by developers to create complex software applications, , and websites. Understanding how to use operators and expressions is a fundamental part of learning Python.
In programming, an operator is usually a symbol or combination of symbols that allows you to perform a specific operation. This operation can act on one or more operands. If the operation involves a single operand, then the operator is unary. If the operator involves two operands, then the operator is binary.
Python divides the operators in the following groups:
Python Arithmetic operators
Arithmetic operators are used with numeric values to perform common mathematical operations:
Python Assignment Operators
Assignment operators are used to assign values to variables:
Python Comparison Operators
Comparison operators are used to compare two values:
Python Logical Operators
Logical operators are used to combine conditional statements:
Python Identity Operators
Identity operators are used to compare the objects, not if they are equal, but if they are actually the same object, with the same memory location:
Python Membership Operators
Membership operators are used to test if a sequence is presented in an object:
Python Bitwise Operators
Bitwise operators are used to compare (binary) numbers:
Operator Precedence
Operator precedence describes the order in which operations are performed.
Example
Parentheses has the highest precedence, meaning that expressions inside parentheses must be evaluated first:
Output:
Example
Multiplication *
has higher precedence than addition +
, and therefor multiplications are evaluated before additions:
Output:
The precedence order is described in the table below, starting with the highest precedence at the top:
Conclusion
In conclusion, operators and expressions are essential components of Python programming that developers should master to write efficient and effective programs. By understanding the different types of operators and how to use them in expressions, programmers can perform different types of operations on values or variables, compare values, perform logical operations, assign values, and test membership and identity, among other things. With Python's wide range of operators, developers can create complex programs quickly and easily. So, whether you are a beginner or an experienced Python developer, mastering the use of operators and expressions is vital for your programming journey.
