Introduction to Python
Python is a high-level, interpreted programming language known for its simplicity and readability. It is widely used in web development, data science, artificial intelligence, automation, and more.
Why Learn Python?
- Easy to Learn: Simple syntax similar to English.
- Versatile: Used for web development, automation, AI, data science, etc.
- Large Community: Many resources and support available.
- Extensive Libraries: Offers libraries for various tasks like NumPy (scientific computing), Pandas (data analysis), TensorFlow (AI), Flask (web development), and more.
Basic Syntax
- Printing Output
print("Hello, World!") - Variables & Data Types
name = "Alice" # String age = 25 # Integer height = 5.6 # Float is_student = True # Boolean - Data Structures
my_list = [1, 2, 3, 4, 5] # List my_tuple = (1, 2, 3, 4, 5) # Tuple my_set = {1, 2, 3, 4, 5} # Set my_dict = {"name": "Alice", "age": 25} # Dictionary - Conditional Statements
age = 18 if age >= 18: print("You are an adult.") else: print("You are a minor.") - Loops
# For Loop for i in range(5): print(i) # While Loop count = 0 while count < 5: print(count) count += 1 - Functions
def greet(name): return f"Hello, {name}!" print(greet("Alice"))
