Write a Python program that solves a quadratic equation $($ax$^2+$ bx $+$ c $=0)$ by taking coefficients $($a$,$ b$,$ and c$)$ as input. The program should handle different cases:

$$ If the discriminant $($b$^2-4$ac$)$ is positive, print two real solutions.

$$ If the discriminant is zero, print one real solution.

$$ If the discriminant is negative, print "Complex solutions.$$

Expected Output:

Enter coefficient a: $1$

Enter coefficient b: $-3$

Enter coefficient c: $2$

Real solutions: $2\mathrm{.}0,1\mathrm{.}0$

Do not use loops or functions
