# Get three numbers, separated by spaces, with no error-recovery.
# If you try to read bad data, the process will fail.
n1, n2, n3 = [float(s) for s in input("Enter three numbers: ").split()]

No more verbose or difficult (certainly not "challenging") than:

var:
  # need to declare these otherwise how will readln
  # know if it is reading floats or ints or strings?
  n1, n2, n3: float
print("Enter three numbers: ")
n1, n2, n3 = readln()


If the use of a list comprehension is too advanced for a beginner in day one,
how about this:

n1 = float(input("Enter a number: ")) n2 = float(input("Enter a number: ")) n3
= float(input("Enter a number: "))
