Find Largest Element of an Array using Function in Python

# Find Largest Element of an Array using Function

# python function to find maximum
# in arr[] of size n
def largest(arr,n):

# Initialize maximum element
max = arr[0]

# Traverse array elements from second
# and compare every element with
# current max
for i in range(1, n):
if arr[i] > max:
max = arr[i]
return max
# Drive Code
arr =[i for i in  range(100)]
   
n = input(" Enter total number of elements(1 to 100):")
n=int(n);

for i in range(n):
    arr[i]=  input(" Enter Number for index {0} ".format(int(i)));


Ans = largest(arr,n)
print ("Largest in given array is",Ans)


   

Swap two variables without using third variable in Python

# Swap two variables without using third variable in Python

a = input(" Please Enter the First Number: ")

a=float(b)+float(a);
b=float(a)-float(b);
a=float(a)-float(b);

Two Number Sum in Python

# Simple Python program to Add Two Numbers

number1 = input(" Please Enter the First Number: ")
number2 = input(" Please Enter the second number: ")

# Using arithmetic + Operator to add two numbers

sum = float(number1) + float(number2)
print('The sum of {0} and {1} is {2}'.format(number1, number2, sum))
