How to Sorted and display the Subclasses of BaseException

[Fernando_7obink]

So, what have you tried? Because, what's the point if you don't try for yourself.

i have done few things e.g.
try to sort the subclass first by sorting the for loop as follow

for subclass in sorted(thisclass.__subclasses__()):

, but it cant work because the sorted() only work on string or number type

then i try to create a list that will consist of the subclass name that already converted to "string" type, so next i can sort that list, then print it, so i try this code

def printExcTree(thisclass, nest = 0):
    if nest > 1:
        print("   |" * (nest - 1), end="")
    if nest > 0:
        print("   +---", end="")

    print(thisclass.__name__)
    
    a = []
    for subclass in thisclass.__subclasses__():
        a.append(subclass.__name__)
        for srt_subclass in a :
            printExcTree(srt_subclass, nest + 1)

printExcTree(BaseException)

and cant work because when it comes to recursion

printExcTree(srt_subclass, nest + 1)

the first parameter pass a str type, meanwhile the

print(thisclass.__name__)

only can work on class type. Is there any way to change the str type becoming a class type e.g. ValueError become "ValueError" then i can change it again "valueError" become ValueError
