Python Installation: Before you can dive into Python programming, you must have Python installed on your computer.
Follow these simple steps to install Python:
Window: Visit the official Python website at python.org . Go to the Downloads section and select the latest version of Python for Windows. Run the installer and make sure to check the “Add Python x.x to PATH” box in the installation process.
macOS: Python usually comes pre-installed on macOS. Open a terminal and type python3 –version to check if Python is installed. Otherwise, you can download the installer from python.org or use package managers like Homebrew.
Linux: Many Linux distributions come with Python pre-installed. Open a terminal and type python3 –version to check if Python is installed. If not, you can use your package manager to install it. For example, on Ubuntu, you can use sudo apt install python3.
Basic Operators and Variables Now that you have Python installed, let’s dive into some basic concepts. Variables: Variables are used to store data in memory. You can think of them as people with values. In Python you do not need to declare the data type explicitly. You can simply assign a value to a variable using the operator. Example: python Copy code no.
x = 5
Name = “John”
Basic implementation: Python supports programs to execute functions on variables and targets. Here are some key features: Mathematical operators: +, -, *, /, % (addition, subtraction, multiplication, division, modulus) .
Comparison operators: ==, !=, <, >, <=, >= (equal, unequal, less than, greater than, less than or equal to, greater than or equal to)
Logical operators: and, or, not (logical AND, or logical, not logical) .
Function operators: =, +=, -=, *=, /= (assign value, .
Command Basics Here are some basic commands and functions that you will use frequently in Python:
print(): The print() function is used to display the result on the screen. You can pass one or more statements to print(), separated by commas. python Copy code no print (“Hello, world!”)
input(): The input() function is used to retrieve user input from the keyboard. It prompts the user with a message and waits for text to be entered. The input is then returned as a string. python Copy code no name = input(“Enter your name: “)
Comments: Your rule is accompanied by comments or explanations. The Python interpreter ignores them. Comments can be single line or multiple lines. Single-character entries begin with a #, while multi-character entries are enclosed in triple quotes (”’). .
