Python for Beginners: Syntax, Functions & Data

Python has readable syntax and is used for scripting, APIs, testing, data analysis and automation. Start by writing small programs you can explain.

What you will learn

CHAPTER 01

Python assigns names directly to values. Type hints help communicate expected values but do not change the runtime type system.

name = "Developer"
level = 1
print(f"Welcome {name}, level {level}")

CHAPTER 02

Use collections to represent multiple values. A dictionary can store key-value data while list comprehensions make simple transformations concise.

people = [{"name": "Avery"}, {"name": "Sam"}]
for person in people:
    print(person["name"])

CHAPTER 03

Keep functions small and return values rather than printing everything. Test functions with edge cases, especially empty and unexpected inputs.

def greet(name: str) -> str:
    return f"Hello, {name}!"

print(greet("CodingPremise"))
