    return agg
  
  def get_average(student):
      homework = average(student["homework"])
      quizzes  = average(student["quizzes"])

here:

return   = 0.1 * homework + 0.3 * quizzes + 0.6 * tests

why would you use a equal sign? we want to return the result of 0.1 * homework + 0.3 * quizzes + 0.6 * tests, not assign it to return (which is what you do by using an equal sign here)

thanks for showing concern, but i have done the correction it’s still showing me error.

what error are you getting?

this line:

  def get_average(student):

has 2 spaces indent, not sure why?
