Answer 2

If you like this also: (list comprehension with max() function and if condition)

print(max([i for i in range(38) if i%2 == 0]))

Answer 3

You could also try:

max(lst, key=lambda n: n*(n%2==0))

Answer 4

yaseer, that‘s a really nice code!

Thanks Lothar

Did you try yourself?

Answer 9

ravindu poorna this will throw an error if there is no even number in given input

Answer 10

ravindu poorna No Problem :)

Answer 11

You're welcome.

Answer 12

Try this logic:
- create a variable "largest" and initialize it with the value -1.
- iterate over the list and for each element, check if it's even.
- if it is even, compare it with the variable "largest" and if the element is greater than "largest", then assign that element to largest.
- when the loop ends, the largest even number will be stored in "largest".
- check if "largest" is equal to -1. If it is, the list contains no even number.

Try yourself once before checking the code.

A more advanced logic:
- use 'filter' to obtain a list of only even integers.
- 'filter' takes first argument as an anonymous function.
- check if length of new list is 0. If it is, no even number exists.
- else use 'max' to find largest number in the list.

Answer 13

max(list) - returns the largest number in a list of integers

Answer 14

#this will return the highest even number

#this will take the user input and make a list
inputNumbers = input ("enter your numbers ")
inputList = list(inputNumbers)

#this will convert the str list into int
for i in range(0,len(inputList)):
inputList[i] = int(inputList[i])

#ths will check for the even numbers
even = list (filter(lambda x:x%2==0,inputList))
if len(even) != 0:
print (max(even))
else:
print ("there is no even numbers")

Answer 15

George Pavlov this won't give the "largest even" number. It simply gives the "largest" number irrespective of whether it's odd or even.

Answer 16

Rohan Agrawal I did fix the problem. Thank you.

Answer 17

George Pavlov check out my answer if you face any trouble.
Happy coding! :)

Answer 18

numbers = list(range(0,10,2))
print(max(numbers))

Answer 19

I tried but not getting the same result

Answer 20

lst=eval(input ("Enter list:"))
length=len(lst)
pos=0
largest=0
while pos<length:
if lst[pos]%2==0:
largest=lst[i]
print(largest even no. is :'')
else:
print ("No even element ")
