Programa de Python para encontrar el número más grande en una lista

Dada una lista de números, la tarea es escribir un programa Python para encontrar el número más grande en la lista dada. Ejemplos:

Input : list1 = [10, 20, 4]
Output : 20

Input : list2 = [20, 10, 20, 4, 100]
Output : 100

Método 1: ordene la lista en orden ascendente e imprima el último elemento de la lista. 

# 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])

# 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))

# 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))

# 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))

# Python code
# To find the largest number in a list
 
def maxelement(lst):
  # displaying largest element
  # one line solution
  print(max(lst))
 
# driver code
# input list
lst = [20, 10, 20, 4, 100]
# the above input can also be given as
# lst = list(map(int, input().split()))  # -> taking input from the user
maxelement(lst)

lst = [20, 10, 20, 4, 100]
print(max(lst, key=lambda value: int(value)) )
