Python program to find largest number in a list
Given a list of numbers, the task is to write a Python program to find the largest number in given list.
Examples:
Input : list1 = [10, 20, 4] Output : 20 Input : list2 = [20, 10, 20, 4, 100] Output : 100Method 1 : Sort the list in ascending order and print the last element in the list.
|
# Python program to find largest
# number in a list
# list of numbers
list1 = [10, 20, 4, 45, 99]
# sorting the list
list1.sort[]
# printing the last element
print["Largest element is:", list1[-1]]
|
Output:
Largest element is: 99Method 2 : Using max[] method
|
# Python program to find largest
# number in a list
# list of numbers
list1 = [10, 20, 4, 45, 99]
# printing the maximum element
print["Largest element is:", max[list1]]
|
Output:
Method 3 : Find max list element on inputs provided by user
|
# Python program to find largest
# number in a list
# creating empty list
list1 = []
# asking number of elements to put in list
num = int[input["Enter number of elements in list: "]]
# iterating till num to append elements in list
for i in range[1, num + 1]:
ele = int[input["Enter elements: "]]
list1.append[ele]
# print maximum element
print["Largest element is:", max[list1]]
|
Output:
Enter number of elements in list: 4 Enter elements: 12 Enter elements: 19 Enter elements: 1 Enter elements: 99 Largest element is: 99Method 4 : Without using built in functions in python:
|
# Python program to find largest
# number in a list
def myMax[list1]:
# Assume first number in list is largest
# initially and assign it to variable "max"
max = list1[0]
# Now traverse through the list and compare
# each number with "max" value. Whichever is
# largest assign that value to "max'.
for x in list1:
if x > max :
max = x
# after complete traversing the list
# return the "max" value
return max
# Driver code
list1 = [10, 20, 4, 45, 99]
print["Largest element is:", myMax[list1]]

Output:
Largest element is: 99Attention geek! Strengthen your foundations with the Python Programming Foundation Course and learn the basics.
