Python Analytics interview questions 1-5

Python Analytics interview questions
In this series, we will add some of the basic questions to start with Python. Slowly we will move to moderate level DSA questions followed by Pandas, Numpy, and OS module.
All you need to do is to install Python in your system and start from scratch.

We will try to solve each question in multiple ways, if you are missing out on the basics then do consult Tutorialspoint or w3school. Invest around 6 hours on these websites and you should be good to go

Python Analytics interview questions

Python Basic Question

1. Take input of two numbers from users and find out the maximum

a = input("Enter first number :")
b = input("Enter second number ")
if a>b:
print(a + " is greater than " + b)
else:
print(b + " is greater than "+a)

or 

a = 30
b = 40
print(a if a>b else b)

or 

a = 10
b = 30
c = max(a,b)
print(c)

2. Print the factorial of any number

a = 10
def fact(n):
if (n == 1 or n==0):
return 1
else:
return n*fact(n-1)
print(fact(5))

or 

import math
print(math.factorial(5))

3. Get square of the number if the number is odd and cube if even

def yoo(n):
if (n%2 == 0):
return nnn
else:
return n*n
print(yoo(3))
print(yoo(2))

4. Print square of first n natural numbers

x = int(input("Enter a natural number = "))
def sum_of_natural(x):
ss = 0
for i in range(1,x):
ss = ss+(i*i)
return ss
print("Sum of square of natural numbers are = " , sum_of_natural(x))

5. Find if a number is an Armstrong number.

Example – 153 is an Armstrong number as 1^3+5^3+3^3 = 153

num = int(input("Enter a number = "))
s = 0
x = num
while (x >0 ):
digit = x%10
s = s+(digitdigitdigit)
x = x//10
print(s)
print("Armstrong" if s == num else "Not Armstrong")
