Crack the logic questions in your campus interview.

Breaking a problem into steps, flowcharts, pseudo-code and the dry-run method. Installing Python, variables, data types, input and output, operators, type conversion.

Practice: swap two numbers without a third variable, simple interest, temperature conversion, area and perimeter problems.

if, elif, else, nested conditions, logical operators, and how to test every edge case before you submit.

Practice: even or odd, leap year, largest of three numbers, grade calculator, triangle type, electricity bill.

for and while loops, range, break, continue, nested loops. The digit-extraction technique that unlocks dozens of interview questions.

Practice: reverse a number, sum of digits, palindrome, Armstrong, prime and primes in a range, perfect and strong numbers, factorial, Fibonacci, GCD and LCM, decimal to binary.

The row-and-column method that lets you build any pattern instead of memorising them. Star, number and alphabet patterns.

Practice: right triangles, pyramids, inverted and hollow shapes, diamond, Floyd's triangle, Pascal's triangle.

Indexing, slicing, immutability, built-in methods, formatting. Solving each problem both with and without built-ins, because interviewers often ask for the manual way.

Practice: reverse a string and its words, palindrome, anagram, vowel and consonant count, character frequency, first non-repeating character, remove duplicates, toggle case, string compression.

List operations, traversal, nested lists and matrices. Linear and binary search, bubble, selection and insertion sort. A first look at time complexity: how to move from a brute-force answer to a better one and explain why.

Practice: largest and second largest, rotate a list, remove duplicates, find the missing number, move zeros to the end, pair with a given sum, merge two sorted lists, matrix addition and transpose.

Counting with dictionaries, set operations, packing and unpacking, and choosing the right collection for the problem.

Practice: word frequency, find duplicates, common elements in two lists, most frequent element, group anagrams.

Parameters, default and keyword arguments, scope, return values. Recursion traced on paper so it finally makes sense. lambda, map, filter and comprehensions.

Practice: recursive factorial, Fibonacci, power, sum of digits, reverse a string, palindrome check, Tower of Hanoi.

Classes and objects, constructors, instance, class and static methods. Encapsulation, inheritance, polymorphism and abstraction with examples you can explain in an interview. Method overriding and dunder methods.

Practice: bank account, student record system, library system, plus the OOP theory questions interviewers ask most often.

Reading, writing and appending files, the with statement, working with folders. try, except, else, finally, raising errors and custom exceptions, so your programs don't crash on bad input.

Practice: count lines and words in a file, copy a file, build a marks report from a file, safe number input.

Meta-characters, quantifiers, character classes, match, search, findall and sub.

Practice: validate mobile numbers, email IDs, PAN, Aadhaar and password strength; extract data from text.
