I have a tkinter program where I have a function generate_report which
in a try block calls the function append_row. This function has also a
try block. When they get an exception they give message. But when
append_row has already given a message then generate_report should
not. To implement this I use the following class:
class AlreadyHandledException(Exception):
pass
Then in append_row I have:
except Exception as err:
messagebox.showerror(error_str,
error_append + '\n\n\n\n' + str(err))
raise AlreadyHandledException()
And in generate_report I have:
except Exception as err:
if type(err).__name__ != "AlreadyHandledException":
messagebox.showerror(error_str,
error_generate + '\n\n\n\n' + str(err))
progress.pack_forget()
Is this an acceptable way, or should I do it differently?
