I want to write a function for f(y) = xy^2 in Python. Like if I pass value such as f(3) then it should give output as 9x. How to do it?

This is very easy. have a look at the following code - 

>>> def f(y):
       return str(y**2) + 'x'
>>> f(9)

'81x'

And if you have the value of constant then 

def f(y):
  x=2
  return x*(y**2)
>>> f(2)
8
>>> 

Suppose you have a polynomial equation such as 

p(x)=x4−4⋅x2+3⋅xp(x)=x4−4⋅x2+3⋅x then in this case :

>>> def p(x):
    return x**4 - 4*x**2 + 3*x
>>> p(2)
