Python Basics Tutorial

Welcome to this basic Python tutorial! Below, you will find essential Python concepts that are fundamental for any beginner.

Printing Output

To print something in Python, use the print() function.

print("Hello, World!")

Variables in Python are created by assigning a value to a variable name.

x = 10
name = "Alice"

A list is a collection of items that can be changed.

fruits = ["apple", "banana", "cherry"]
print(fruits[0]) # Accessing the first item, which is "apple"

A dictionary is a collection of key-value pairs.

person = {"name": "Alice", "age": 25}
print(person["name"]) # Outputs: Alice

Loops in Python are used to iterate over a sequence of items.

Use a for loop to iterate over items of a list.

fruits = ["apple", "banana", "cherry"]
for fruit in fruits:
    print(fruit)

Use a while loop to repeat an action until a condition changes.

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

Conditional statements are used to perform different computations or actions depending on whether a condition is true or not.

if age >= 18:
    print("Adult")
elif 13 < age < 18:
    print('Teenager')
else:
    print("Too young to drink")

Functions are blocks of code that perform a specific task and can be reused.

def greet(name):
    return f"Hello {name}!"

print(greet("Bob"))
