How do I find the maximum value in a list in Python?

How do I find the maximum value in a list in Python?

You can use the built-in max() function to find the maximum value in a list. For example, max([1, 2, 3, 4]) will return 4.

What if my list contains negative numbers?

The max() function works with negative numbers too. For instance, max([-1, -2, -3]) will return -1.

Can I find the maximum value in a list of strings?

Yes, you can! The max() function will return the string that is lexicographically greatest. For example, max(['apple', 'banana', 'cherry']) will return 'cherry'.

Is there a way to find the maximum value without using the max() function?

Absolutely! You can iterate through the list and keep track of the maximum value manually. Here's a simple example:

max_value = my_list[0]
for num in my_list:
    if num > max_value:
        max_value = num
