Welcome to the Python Basics section of our community! Python is a versatile programming language used for various applications including web development, data analysis, artificial intelligence, and more. Below are some fundamental concepts to help you get started with Python.
Install Python
Before diving into coding, you need to install Python on your system. You can download the latest version from the official Python website.
Basic Syntax
Indentation
Python uses indentation to define blocks of code. Proper indentation is crucial as it determines the structure of your program.
if condition:
# Block of code
Variables
Variables in Python are dynamically typed, which means you don't have to declare the type of a variable before using it.
x = 10
name = "John"
Data Types
Python has several built-in data types such as integers, floats, strings, lists, dictionaries, and tuples.
age = 25
height = 5.5
message = "Hello, World!"
Control Flow
Control flow statements allow you to control the execution of your code based on certain conditions.
If-Else Statement
if x > 10:
print("x is greater than 10")
else:
print("x is not greater than 10")
For Loop
for i in range(5):
print(i)
While Loop
i = 0
while i < 5:
print(i)
i += 1
Functions
Functions are reusable blocks of code that perform a specific task.
def greet(name):
return "Hello, " + name
print(greet("John"))
