Question

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

Answer 1

The function can be written in two ways:

1. Using the max() function of the list
2. Using for loop to iterate every element and check 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​
