nameerror when trying to call a function in a class

Question

I was trying to print the index of the values in a string but I keep on running to the error NameError: name 'findWithException' is not defined but I defined it right below the class. What is causing this? Any help is appreciated. Thanks in advance.

class MyString(str):
    def findWithException(s, c):
        try:
            x = s.index(c)
            print(x)
        except:
            print("Not found")
s = MyString("abcdef")
findWithException(s, "c")

Answer 1

I guess that's what you wanted to acheive:

class MyString(str):

    def find_with_exception(self, c):
        try:
            x = self.index(c)
            print(x)
        except:
            print("Not found")


s = MyString("abcdef")
s.find_with_exception("c")

Edit , after you clarified your issue:

def findWithException(s, c):
    if c in s:
        x = s.index(c)
        print(x)
    else:
        print("Not found")

That's just what you seem to need.
