7. To write a python program find the maximum of a list of numbers.

 def find_max(nums):

    max_num = float('-inf')

    for num in nums:

        if num > max_num:

            max_num = num

    return max_num

# Example usage

nums = [1, 2, 5, 3, 7, 2, 8, 4]

print(find_max(nums)) # Output: 8
