I am trying to have math equations not end up with +0j at the end. This is what I currently have

from cmath import sqrt
a = int(input("insert number: "))
b = int(input("insert number: "))
exp = input("Would you like to have exponents? ")
function = input("Put what kind of equasion you want: ")
if function == "*" or "multiplication" or "MULTIPLICATION" or "Multiplication":
    if exp == "yes" or "Yes" or "YES":
        e = int(input("What number do you want?"))
        root = input("Would you like square root? ")
        if root == "yes":
            c = int(sqrt(a * b))
            d = c ** e
            print(a, "was", function, "by", b, "getting the answer of", c)
        print("Then", c, "was put to the power of", e, "giving the final answer of", d)

When I run it, the final number (which appears where variable d is) ends up have a +0J at the end. What would I need to add or remove to get that to not happen? I was told it might be something with the function variable I have that is causing the problem but I am not sure how I could get the function out of a string.

So don't use a complex number? `+ 0j` is part of the string representation of `complex` instances – DeepSpace Oct 06 '22 at 13:08
it depends what you enter, `+0j` is a complex number, debug the code to determine when a result gets complex – rioV8 Oct 06 '22 at 13:08

Side note: [Why does "a == x or y or z" always evaluate to True? How can I compare "a" to all of those?](https://stackoverflow.com/q/20002503) – 001 Oct 06 '22 at 13:09
@rioV8 `cmath.sqrt` returns a `complex` instance (guess what the `c` in `cmath` stands for :) ) – DeepSpace Oct 06 '22 at 13:09
@DeepSpace where would ```cmath.sqrt``` go? – Ruby Rose Oct 06 '22 at 13:10
`d` does not have a value in all paths. – rioV8 Oct 06 '22 at 13:10
@JohnnyMopp kind of, I just need to know where the ```cmath.sqrt``` would go – Ruby Rose Oct 06 '22 at 13:11
@rioV8 how does ```d``` not have a value? – Ruby Rose Oct 06 '22 at 13:13

Why not use `math` instead of `cmath`? – John Coleman Oct 06 '22 at 13:13
@JohnColeman where would ```math``` go? – Ruby Rose Oct 06 '22 at 13:15
I figured out where ```math``` would go – Ruby Rose Oct 06 '22 at 13:17
You could simply delete the character `c` in `from cmath import sqrt`. – John Coleman Oct 06 '22 at 13:17

find all the paths of your program and determine if all variables have a valid value – rioV8 Oct 06 '22 at 14:52
