Sometimes, while working with Python, we can have a problem in which we need to get maximum of list. But sometimes, we need to get this for between custom indices. This can be need of any domain be it normal programming or web development. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using loop + max()
This is brute force method in which we performed this task. In this, we just add to new list the elements in specified range. Then max() is used to compute maximum.




# Python3 code to demonstrate 
# Maximum element in Cropped List
# using loop + max()
  
# initializing list 
test_list = [2, 3, 5, 7, 9, 10, 8, 6]
  
# printing original list
print ("The original list is : " + str(test_list))
  
i, j = 2, 5
  
# Maximum element in Cropped List
# using loop + max()
res = []
for idx, ele in enumerate(test_list):
    if idx >= i and idx < j:
        res.append(ele)
res = max(res)
  
# printing result 
print ("The maximum element in range is : " + str(res))

Output :

The original list is : [2, 3, 5, 7, 9, 10, 8, 6]
The maximum element in range is : 9

 

Method #2 : Using list slicing + max()
The combination of above functions can be used to perform this task. In this, we just perform slicing using list slicing and max() performs the task of extracting max.




# Python3 code to demonstrate 
# Maximum element in Cropped List
# using list slicing + max()
  
# initializing list 
test_list = [2, 3, 5, 7, 9, 10, 8, 6]
  
# printing original list
print ("The original list is : " + str(test_list))
  
i, j = 2, 5
  
# Maximum element in Cropped List
# using list slicing + max()
res = test_list[i : j]
res = max(res)
  
# printing result 
print ("The maximum element in range is : " + str(res))

Output :

The original list is : [2, 3, 5, 7, 9, 10, 8, 6]
The maximum element in range is : 9
