operators in python
In Python, operators 🔍 are special symbols or keywords that perform some operations on one or more operands 🔢. In this lesson
, we will learn about operators and different types 📊 of operators 🔢 in Python.
What are Operators?
Operators are symbols or words that represent an action or process. They have commonly used in programming 💻 and mathematics 🧮 to manipulate data or perform calculations. Operators can be classified into different categories, such as arithmetic, relational, logical, and bitwise, each with its own rules and functions. Arithmetic operators perform mathematical operations like addition ➕, subtraction ➖, multiplication ✖️, and division ➗.Relational operators compare two values and return a Boolean value based on the comparison result. Logical operators combine multiple conditions and return a Boolean value based on the outcome of the mixed conditions. Bitwise operators perform operations on the binary representation of values. Operators are essential for building complex algorithms and functions in programming. Understanding the different types of operators and their functions is necessary to write code effectively and solve problems.
Different Types of Operators
There are several types of operators in Python, which can be classified as follows:
Arithmetic operators are a fundamental part of mathematics and computer programming . They represent mathematical operations such as addition , subtraction , multiplication , and division . These operators are used to perform calculations and manipulate numerical data 🔢. It is essential to clearly understand these operators to work with and analyze numerical data effectively 💻. We have arithmetic operators like:
In the manufacturing industry, tracking the production of different products and understanding how various factors impact the production process is essential. Arithmetic operators are critical tools in Python that allow you to perform mathematical operations on variables representing production data.
production_rate = 100 increase = 25 decrease=20 total_products = 1000 defect_rate = 0.05 total_units = 50 new_production_rate = production_rate + increase print(new_production_rate)#addition new_production_rate = production_rate - decrease print(new_production_rate)#substraction defective_products = total_products * defect_rate print(defective_products)#multiplication cost_per_unit = production_cost / total_units print(cost_per_unit)#division cost_per_unit = production_cost // total_units print(cost_per_unit) #floor division(gives values before decimal) cost_per_unit = production_cost % total_units print(cost_per_unit) #modulus(returns remainder)
Comparison operators are utilized to compare values and return a Boolean True or False value. They include the equality operator (==), inequality operator (!=), greater than operator (>), less than operator (<), greater than or equal to the operator (>=), and less than or equal to the operator (<=).
product_type = "Widget" order_status = "Fulfilled" production_rate = 1000 target_rate = 900 defect_rate = 10 quality_threshold = 100 production_cost = 2000 target_cost = 1000 order_quantity = 900 available_inventory = 1200 print(product_type == "Widget") #equality check print(order_status != "Fulfilled") #inequality check print(production_rate > target_rate) #greater than print(defect_rate < quality_threshold) #less than print(production_cost >= target_cost) #greater than equal to print(order_quantity <= available_inventory) #less than equal to
These are used to combine multiple conditions and return a Boolean ✅ value. These operators work like tools a farmer would use to sort their apples into different baskets based on multiple conditions, such as size and color.
product_A_production_rate = 10 product_B_production_rate =20 assembly_line_1_status = "running" assembly_line_2_status = "not running" product_defect_rate = 0.02 print(product_A_production_rate > 0 and product_B_production_rate > 0) print(assembly_line_1_status == "running" or assembly_line_2_status == "running") print(not product_defect_rate >= 0.05)
These operators are utilized to perform bitwise operations on binary numbers. They include the bitwise and operator (&), the bitwise or operator (|), the bitwise exclusive or operator (^), the bitwise left shift operator (<<), and the bitwise right shift operator (>>).
product_A = 0b10101010 product_B = 0b11001100 print(product_A & product_B) #and print(product_A | product_B) #or print(product_A ^ product_B) #xor print(product_A << 2) #left shift print(product_A >> 2) #right shift
These operators are utilized to assign a value to a variable. They include the equal to the operator (=), the plus equal to the operator (+=), the minus equal to the operator (-=), the multiply equal to the operator (*=), and the divide equal to the operator (/=).
production_rate=50 production_rate += 40 print(production_rate) production_rate -= 20 print(production_rate) production_rate *= 5 print(production_rate) production_rate /= 10 print(production_rate)
This lesson explains what operators are in Python and the different types of operators, including arithmetic, comparison, , logical, and assignment operators. Operators are tools that help manipulate values and make decisions based on them, just like a 🧑🌾 farmer needs tools to count and sort apples.
