About Python

Python is an interpreted, high-level, general-purpose programming language. Created by Guido van Rossum and first released in 1991, Python's design philosophy emphasizes code readability with its notable use of significant whitespace.

Python is dynamically typed and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented, and functional programming.

"Python is powerful... and fast; plays well with others; runs everywhere; is friendly & easy to learn; is Open."

Python Syntax Basics

Variables

# Variable assignment
x = 5
y = "Hello, World!"
z = [1, 2, 3]

Functions

# Function definition
def greet(name):
    return f"Hello, {name}!"

# Function call
print(greet("Alice"))

Loops

# For loop
for i in range(5):
    print(i)

# While loop
count = 0
while count < 5:
    print(count)
    count += 1

Conditionals

# If-elif-else
age = 18
if age < 13:
    print("Child")
elif age < 18:
    print("Teen")
else:
    print("Adult")
