Consider the following Python function to find the maximum number in a list:

def find_max(numbers):
    max_num = numbers[0]
    for num in numbers[1:]:
        if num > max_num:
            max_num = num
    return max_num

numbers = [5, 3, 8, 6, 7]
max_number = find_max(numbers)
print("The maximum number is: ", max_number)

What is the issue with this code?

• The function does not correctly find the maximum number.

• The print statement is outside the function.

• There is no issue; the code works as intended.

• The list should be sorted before finding the maximum number.

• The initial max_num should be set to None.

def calculate_sum():\n if y == 5:\n return y + 5\n elif y == 10:\n return y + 10\n\nWhat are the issues with this function?

• Indentation error in line 2

• Indentation error in line 4

• Variable 'y' is not defined within the function

• There are no issues with the function
