Скачать или смотреть Programmer Music - Variables and Data Types (Discovering Python: A Beginner's Journey)

Welcome to the next step in our programming journey – mastering variables and data types. Remember the excitement of learning how to store and manipulate information? This track reflects the curiosity and satisfaction of understanding these fundamental concepts.

Imagine the moment when you first grasped how to use variables to hold data and saw the potential they unlocked. From numbers to text, learning to manage different data types was a key milestone. The room was filled with a sense of discovery as you experimented with different variables and saw how they interacted in your code.

Beginner Cheat Sheet:

Variables:
☑️ x = 5 (integer)
☑️ name = "Alice" (string)
☑️ is_active = True (boolean)

Data Types:
☑️ int (Integer): Whole numbers, e.g., 10
☑️ float (Floating point): Decimal numbers, e.g., 10.5
☑️ str (String): Text, e.g., "Hello"
☑️ bool (Boolean): True or False, e.g., True
☑️ list (List): Ordered collection, e.g., [1, 2, 3]
👉 Access: list_name[index], e.g., my_list[0]
☑️ dict (Dictionary): Key-value pairs, e.g., {"name": "Alice", "age": 25}
👉 Access: dict_name[key], e.g., my_dict["name"]

Type Conversion:
☑️ int("10") converts string to integer
☑️ str(10) converts integer to string
☑️ list("hello") converts string to list of characters

Useful Functions:
☑️ type(variable) to check the type of a variable
☑️ len(collection) to get the length of a list, string, or dictionary
☑️ max(collection): Find the maximum value in a list or set
☑️ min(collection): Find the minimum value in a list or set
☑️ sum(collection): Calculate the sum of all elements in a list
☑️ sorted(collection): Return a sorted list of elements
