how to find the largest number in a list python code example

Example 1: program to find the largest of three numbers in python

# Python program to find the largest number among the three input numbers
# take three numbers from user
num1 = float(input("Enter first number: "))
num2 = float(input("Enter second number: "))
num3 = float(input("Enter third number: "))

if (num1 > num2) and (num1 > num3):
   largest = num1
elif (num2 > num1) and (num2 > num3):
   largest = num2
else:
   largest = num3

print("The largest number is",largest)

Example 2: python largest value in list

>>> list = [1, 3, 2, 0]
>>> max(list)
3

Example 3: Write a function that returns the largest element in a list

def return_largest_element(array):
    largest = 0
    for x in range(0, len(array)):
        if(array[x] > largest):
            largest = array[x]
    return largest

Example 4: python how to find the highest even in a list

def highest_even(li):
  evens = []
  for item in li:
    if item % 2 == 0:
      evens.append(item)
  return max(evens)

print(highest_even([10,2,3,4,8,11]))


# Building a function to find the highest even number in a list

Example 5: find the largest size in a list - python

longest_string = len(max(a_list, key=len))
