I'm not sure what you mean by "validate", perhaps if you shared the code where the validation will be performed and/or a link to the page you are working with?

But it sounds like you may just need to perform a test. So, assuming your value was stored in a variable named "val":

if val < 0 or val > 100:
    print("The value is out of range.")

i was given a task , Task: 'Start a new Python script and write some suitable input commands to store three items of data into three variables: Student Name, Coursework Mark, and Exam Mark. The inputs for coursework mark and exam mark should be validated as a value in the range 0-100%.', i didnt know how to do this part , "The inputs for coursework mark and exam mark should be validated as a value in the range 0-100%. "

So perhaps you might incorporate that test in a loop to retry input:

while True:
    coursework = int(input("Enter the Coursework Mark: "))
    if coursework < 0 or coursework > 100:
        print("The value is out of range, try again.")
    else:
        break
