Question

Write a function that returns the largest element of the list passed as parameter.

Answer 1

The function can be written in two ways:

1. Using max() function of the list
2. Using for loop to iterate every element and checking for the maximum value

Program 1:

#Using max() function to find largest number

def largestNum(list1):

l = max(list1)

return l

list1 = [1, 2, 3, 4, 5, 6, 7, 8, 9]

#Using largestNum function to get the function

max_num = largestNum(list1)

#Printing all the elements for the list

print("The elements of the list",list1)

#Printing the largest num

print("\nThe largest number of the list:",max_num)

OUTPUT:

The elements of the list [1, 2, 3, 4, 5, 6, 7, 8, 9]

The largest number of the list: 9​

Program 2:

​#Without using max() function of the list

def largestNum(list1):

length = len(list1)

num = 0

for i in range(length):

if(i == 0 or list1[i] > num):

num = list1[i]

return num

list1 = [1, 2, 3, 4, 5, 6, 7, 8, 9]

#Using largestNum function to get the function

max_num = largestNum(list1)

#Printing all the elements for the list

print("The elements of the list",list1)

#Printing the largest num

print("\nThe largest number of the list:",max_num)

OUTPUT:

The elements of the list [1, 2, 3, 4, 5, 6, 7, 8, 9]

The largest number of the list: 9​
