Is there something wrong?

Question

Im new to python and i wanted to make a program calculating the Discriminant of an quadratic equation.
But At d=0: there is an error syntax someone help please^^

# File: Discriminant.py
# This program calculates the discriminant of a quadratic equation. With a<0 or a>0

def discriminant():
print("The quadratic equation is ax^2+bx+c=0")
a =eval(input("The a value:"))
b =eval(input("The b value:"))
c =eval(input("The c value:"))

import cmath

a=1
b=-2
c=1

d = (b**2)-4*(a*c)

if d>0:
sol1= (-b+cmath.sqrt(d))/(2*a)
sol2= (-b-cmath.spqrt(d))/(2*a)
else if d=0:
sol=-b/2*a
else if d<0:
print("error")

Answer 1

else if ==> elif
if d=0 ==> if d==0

Answer 2

Anna Thank you so much!

Answer 3

Anna Well there isn't any output for it 0.0 shouldn't it be?

Answer 4

There is no print statement for the case that d==0. It will only print "error" if d<0

Answer 5

Anna generally aftet i made the input order it didn't generate anything as an output for the whole code
