Nowadays in any interview a programming test is a must, So here we are creating a series of basic interview program in Python, We learn step by step. You can also visit Java program if you are looking for that

## Write a program in Python to find a Maximum of two numbers

If you have two numbers, write a Python code to find the limit of these two numbers.

```
def max(i, j):
if i >= j:
return i
else:
return j
a = 2
b = 4
print(max(a, b))
print('Thank you for reading basic interview programs in python')
```

## Write a program in Python for calculation of simple interest

we can use simple interest formula :

Simple Interest = (P x T x R)/100

Where,

P is the principle amount

T is the time and

R is the rate

```
def simple_interest(p,t,r):
print('The principal is', p)
print('The time period is', t)
print('The rate of interest is',r)
si = (p * t * r)/100
print('The Simple Interest is', si)
return si
# Driver code
simple_interest(20000, 3, 8)
print('Thank you for reading basic interview programs in python')
```

## Write a program in Python for check whether the number is Armstrong number or not

The Armstrong number of three digits is the integer such that the sum of the cubes of its digits is equal to the number itself.

## Write a program in Python to find some of the square of first n natural numbers

```
def squaresum(n) :
sm = 0
for i in range(1, n+1) :
sm = sm + (i * i)
return sm
n = 4
print(squaresum(n))
print("Thanks for visiting onurdesk program in Python")
```

## Write a program in Python to sum of all digits of a number

```
n=int(input("Enter a number:"))
sum=0
while n>0:
rem=n%10
sum=sum+rem
n=int(n/10)
print("The sum of digits of number is:", sum)
print("Thanks for visiting onurdesk program in Python")
```

## Write a program in Python to check a year is a leap year or not using Python

```
year=int(input("Enter a Year:"))
if ((year % 100 == 0 and year % 400 == 0) or (year % 100 != 0 and year % 4 == 0)):
print("It is a Leap Year")
else:
print("It is not a Leap Year")
```

## Write a program in Python to convert Days into years, weeks and months

```
days=int(input("Enter Day:"))
years =(int) (days / 365)
weeks =(int) (days / 7)
months =(int) (days / 30)
print("Days to Years:",years)
print("Days to Weeks:",weeks)
print("Days to Months:",months)
```

## Write a program in Python to print all prime number in an interval

```
start = 11
end = 25
for val in range(start, end + 1):
# If num is divisible by any number
# between 2 and val, it is not prime
if val > 1:
for n in range(2, val):
if (val % n) == 0:
break
else:
print(val)
print("Thanks for visiting program in Python")
```

## Write a program in Python to find Area of a circle

```
def findArea(r):
PI = 3.142
return PI * (r*r);
#Like us on facebook
# Driver method
print(findArea(5))
print("Thanks for visiting program in Python")
```

## Write a program in Python find sum of elements in given array

```
def _sum(arr,n):
# return sum using sum
# inbuilt sum() function
return(sum(arr))
# driver function
arr=[]
# input values to list
arr = [12, 3, 4, 15]
# calculating length of array
n = len(arr)
ans = _sum(arr,n)
#Like us on facebook
# display sum
print("Thanks for visiting onurdesk program in Python")
print (ans)
```

## Write a program in Python to check if small string is there in big string

```
def check(string, sub_str):
if (string.find(sub_str) == -1):
print("NO")
else:
print("YES")
print("Like us on facebook")
print("Thanks for visiting onurdesk program in Python")
# driver code
string = "zeus is a programmer"
sub_str ="zeus"
check(string, sub_str)
```
