### Python: How to find List Max & Min Easily

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.

## Python: Find Max and Min in a List

You can achieve this by writing a user-defined function. Here's useful logic and steps to write it precisely.

• 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 have written the maxmin.py file in Ubuntu. The function name is  "findmaxmin ". ## Result

Below command to enter Python. This command, you can issue in Ubuntu where python3 is installed

\$ python3

You have now entered Python3.

>>> import maxmin

You will prompt a message that imported successfully without any syntax errors.

Code in the Python Script Below commands, I have issued.

>>> data = (109, 98, 88, 7)
>>> maxmin.findmaxmin(data)

The result is (109, 7)
