🐍 Python Basic Syntax Tutorial
Learn Python fundamentals step by step with hands-on examples
Hello World & Print Statements
Start with the classic 'Hello World' program and learn how to display output
# Your first Python program
print("Hello, World!")
print("Welcome to Python programming!")
# Print multiple values
print("Name:", "Alice", "Age:", 25)Variables & Data Types
Store and work with different types of data in Python
# Basic data types
name = "Alice" # String
age = 25 # Integer
height = 5.6 # Float
is_student = True # Boolean
hobbies = ["reading", "coding", "gaming"] # List
# Check data types
print(type(name)) # <class 'str'>
print(type(age)) # <class 'int'>String Formatting
Learn different ways to format and combine strings with variables
# F-strings (recommended)
print(f"My name is {name}, I'm {age} years old")
# Format method
print("Hello {}, you are {} years old".format(name, age))
# String concatenation
print("Name: " + name + ", Age: " + str(age))Control Structures
Make decisions in your code using if/else statements
# If-else statements
if age >= 18:
print("You're an adult!")
elif age >= 13:
print("You're a teenager!")
else:
print("You're a child!")
# Comparison operators: ==, !=, <, >, <=, >=
# Logical operators: and, or, notLoops & Iteration
Repeat actions and iterate through collections of data
# For loops
for hobby in hobbies:
print(f"I enjoy {hobby}")
# Range function
for i in range(5):
print(f"Count: {i}")
# While loops
count = 0
while count < 3:
print(f"Loop {count}")
count += 1Functions
Create reusable blocks of code to organize your programs
# Define a function
def greet(name, age=18):
return f"Hello {name}, you are {age} years old!"
# Call the function
message = greet("Python", 32)
print(message)
# Function with multiple return values
def calculate(x, y):
return x + y, x - y, x * y
add, sub, mul = calculate(10, 5)Python Project Ideas
