Understanding Data Type Conversions in Python
Python supports several core data types, each with distinct characteristics:
Numeric Types: int, float, bool, complex
Strings: Enclosed in single or double quotes, using ASCII characters
Lists: Ordered, mutable collections of items separated by commas
Tuples: Ordered, immutable collections enclosed in parentheses
Dictionaries: Key-value pairs ...

Python List Fundamentals: Indexing, Slicing, and Common Operations
A list in Python is an ordered, mutable collection that can store elements of mixed types.
tech_stack = ['Python', 'Go', 'Rust', 'Java', 'Kotlin']
print(tech_stack)
Output:
['Python', 'Go', 'Rust', 'Java', 'Kotlin']
The type() function confirms the object class:
tech_stack = ['Python', 'Go', 'Rust', 'Java', 'Kotlin']
print(type(tech_stack))
...

Creating Lists
LPUSH
The LPUSH command adds one or more elements to the beginning of a list.

Comprehensive Guide to Python's Nine Fundamental Data Types
Integer (int)
The int type represents whole numbers in Python, including positive, negative, and zero values. Unlike many other programming lagnuages, Python integers have arbitrary precision, meaning they can grow as large as memory allows.

Determining List Length in Python
Understanding List Size in Python
Unlike certain programming languages such as Java, Python does not provide a .size attribute for lists. Instead, the built-in len() function is used to determine the number of elements within a list.
Retrieving List Length
The len() function acepts any sequence type—such as lists, tuples, or strings—and returns ...
