Common Python Utility Functions for Data Manipulation
Understanding Python Slicing with [::-1] for Reversal
Python's slicing syntax offers a versatile way to manipulate sequences like strings, lists, and tuples. The general format for slicing is sequence[start:end:step]. A particularly common and powerful application is reversing a sequence using [::-1].
When you omit start and end, Python assumes ...

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))
...
