The lists in Python can handle different type of datatypes in it. The manipulation of such lists is complicated. Let’s say we have a problem in which we need to find the min/max integer value in which the list can contain string as a data type i.e heterogenous. Let’s discuss certain ways in which this can be performed.
Method #1 : Using list comprehension +
min()/max() + isinstance()
This particular problem can be solved by filtering our search of min/max using the isinstance method, we can filter out the integer value and then can use min/max function to get required min/max value.
The original list is : [3, 'computer', 5, 'geeks', 6, 7] The minimum value in list is : 3
Method #2 : Using
lambda + key + max()/min() + isinstance()
The above problem can also be solved using the lambda function as a key in the min()/max() along with the isinstance method which performs the task of checking for integer values.
The original list is : [3, 'computer', 5, 'geeks', 6, 7] The maximum value in list is : 7
