Here's logic to find Max and Min values in a List. Without using built-in Max() and Min () functions you can find Max and Min values in a List. For that matter, you need to write a user-defined function. This post is all about how to write it and run. Finding Max and Min in List You can achieve this by writing a user-defined function. Here's useful logic and steps to write it precisely. IN THIS PAGE Write a Function Execute Function Get the result Write Function You can write an user-defined function to get MAX and MIN values. In this function, I am using the max(), min() built-in functions. The other variables you can use as you wish. Below is the my actual logic. Sample Code def findmaxmin (data): ax = max (data) by = min (data) return (x,y) data = ( 109 , 98 , 88 , 7 ) (maximum, minimum) = findmaxmin (data) print ( "Maximum Marks = " , maximum) print ( "Minimum Marks = " , minimum) Created a Script Using vim editor Here as the first step, I ...

Here're the quick differences between Tuple and List in Python. These are helpful for interviews and your project. Tuple and List differences List Comma-separated elements inside a square bracket [] make a list. The elements are indexed, which starts from '0' These you need to enclose in a single quote and separate by a comma. It can contain another list, which is called a NESTED list. Use type() function to get the type of data it is. The list is mutable (you can change the data). The objects (elements) can be of different data types.  Here're  examples on the List. Tuple The elements comma-separated and enclosed in parenthesis ()  The elements are indexed, which starts from '0' It can have heterogeneous data (integer, float, string, list, etc.) It is immutable. So you can't change the elements. Use the type() function to get the type of data it is.  Here're  examples of Tuple. List Example #Illustration of creating a list  new_list=[1, 2, 3, 4]  prin...
