Python program to obtain the marks in computer of some student and find mean median and mode

# Function to get marks from user

        marks.append(mark)

# Function to calculate mean
def calculate_mean(marks):
    return sum(marks) / len(marks)

# Function to calculate median

    marks.sort()
    n = len(marks)
    mid = n // 2
    if n % 2 == 0:  # even number of elements
        median = (marks[mid - 1] + marks[mid]) / 2
    else:  # odd number of elements
        median = marks[mid]
    return median

# Function to calculate mode

    frequency = {}

            frequency[mark] += 1
