Cracking MNC interviews requires strong fundamentals and clean coding logic. Below are 20 commonly asked small Python programs that test problem-solving, clarity, and understanding of core concepts.
1️⃣ Reverse a String
s = "Python"
print(s[::-1])
2️⃣ Check Palindrome
s = "madam"
print(s == s[::-1])
3️⃣ Swap Two Numbers (Without Temp)
a, b = 5, 10
a, b = b, a
print(a, b)
4️⃣ Find Factorial
def factorial(n):
return 1 if n == 0 else n * factorial(n-1)
print(factorial(5))
5️⃣ Fibonacci Series
a, b = 0, 1
for _ in range(5):
print(a, end=" ")
a, b = b, a+b
6️⃣ Find Largest Element in List
nums = [4, 7, 1, 9]
print(max(nums))
7️⃣ Remove Duplicates from List
nums = [1,2,2,3,4,4]
print(list(set(nums)))
8️⃣ Count Character Frequency
from collections import Counter
print(Counter("python"))
9️⃣ Check Prime Number
n = 7
print(all(n % i != 0 for i in range(2, n)))
🔟 Find Second Largest Number
nums = [10, 20, 4, 45]
nums.sort()
print(nums[-2])
1️⃣1️⃣ Merge Two Dictionaries
d1 = {"a":1}
d2 = {"b":2}
print({**d1, **d2})
1️⃣2️⃣ Find Missing Number in Range
nums = [1,2,4,5]
n = 5
print(n*(n+1)//2 - sum(nums))
1️⃣3️⃣ Sort List of Tuples
data = [(1,3),(3,1),(5,2)]
print(sorted(data, key=lambda x: x[1]))
1️⃣4️⃣ Check Anagram
s1, s2 = "listen", "silent"
print(sorted(s1) == sorted(s2))
1️⃣5️⃣ Flatten Nested List
nested = [[1,2],[3,4]]
print([item for sub in nested for item in sub])
1️⃣6️⃣ Find Common Elements
a = [1,2,3]
b = [2,3,4]
print(list(set(a) & set(b)))
1️⃣7️⃣ Generate Random Number
import random
print(random.randint(1,10))
1️⃣8️⃣ Check Armstrong Number
n = 153
print(n == sum(int(d)**3 for d in str(n)))
1️⃣9️⃣ Count Vowels
s = "hello world"
print(sum(1 for c in s if c in "aeiou"))
2️⃣0️⃣ Find GCD
import math
print(math.gcd(24, 36))
