Programming (Python)
Sharpen your Python programming skills for coding interviews and placement tests. From data structures to common gotchas that interviewers love to test.
Python Dictionaries
A Python dictionary is a mutable collection of key-value pairs with O(1) average lookup time.
Dictionaries are essential for fast lookups, counting, grouping, and caching. Most coding interviews test dictionary manipulation.
Python Lists
A Python list is a mutable, ordered collection that can hold items of any type.
Lists are the most-used data structure in Python. Every coding interview and placement test assumes you know list operations, slicing, and common patterns.
Python String Methods
Python strings are immutable sequences of characters with a rich set of built-in methods for manipulation.
String manipulation is the most common topic in coding interviews. Understanding immutability and method chaining is essential.
