# Python – Maximum element till K value

• Last Updated : 29 Dec, 2019

One of the problem that is basically a subproblem for many complex problems, finding maximum number till a certain number in list in python, is commonly encountered and this particular article discusses possible solutions to this particular problem.

Method #1 : Naive method
The most common way this problem can be solved is using a loop and just max the occurrences of elements that are till given number K.

 `# Python 3 code to demonstrate ``# Maximum element till K value``# using naive method `` ` `# initializing list``test_list ``=` `[``1``, ``7``, ``5``, ``6``, ``3``, ``8``]`` ` `# initializing k``k ``=` `4`` ` `# printing list ``print` `(``"The list : "` `+` `str``(test_list))`` ` `# using naive method ``# Maximum element till K value``res ``=` `0``for` `i ``in` `test_list :``    ``if` `i <``=` `k :``        ``res ``=` `max``(res, i)`` ` `# printing the intersection ``print` `(``"The maximum number till K : "` `+` `str``(res))`
Output :
```The list : [1, 7, 5, 6, 3, 8]
The maximum number till K : 3
```

Method #2 : Using list comprehension
This method achieves this task in a similar way, but in a more concise manner. List comprehension always lowers the lines of codes in the program even though runs a similar approach in the background.

 `# Python 3 code to demonstrate ``# Maximum element till K value``# using list comprehension`` ` `# initializing list``test_list ``=` `[``1``, ``7``, ``5``, ``6``, ``3``, ``8``]`` ` `# initializing k``k ``=` `4`` ` `# printing list ``print` `(``"The list : "` `+` `str``(test_list))`` ` `# using list comprehension``# Maximum element till K value``res ``=` `max``([i ``for` `i ``in` `test_list ``if` `i <``=` `k])`` ` `# printing the intersection ``print` `(``"The maximum number till K : "` `+` `str``(res))`
Output :
```The list : [1, 7, 5, 6, 3, 8]
The maximum number till K : 3
```
