Midpoint finder function practice STUCK

Get Help Python
#1

While practicing writing a function that takes 2 lists as input:

  def midpt_generator([x1, y1], [x2, y2]):
    midpt = [(x1 + x2)/2 , (y1 + y2)/2)]
    return midpt

This should find the midpoint of a coordinate pair. Input is the two coordinate points (entered as lists) , function should perform operation on the values from the lists, and return the midpoint (a new list, coordinate pair). What is the syntax error here?

#2

You are defining the function parameters as [x1,y1] and [x2,y2]. You should be using variable names. Then inside your function, access the array information with those variable names
