I knew that you can just chain try/except blocks, and it's how I do it now, but the example I provided wasn't very realistic.

Take for example the initialization of a class from a config file, config file which may or may not have certain keys in it. With many keys, it is very inconvenient to chain try/except blocks to handle every possible case. Having the continue keyword would prove useful to put several error prone lines of code into a single try block, and have the execution continue as normal at tge statement after the statement errored out

I propose to be able to use the continue keyword to continue the execution of the try block even when an error is handled. The above could then be changed to :


    try:
        i = int("string")
        print("continued on")
        j = int(9.0)
    except ValueError as e:
        print(e)
        continue

>>> "invalid literal for int() with base 10: 'string'"
>>> "continued on"

There is already a much simpler way of doing this:

    try:
        i = int("string")
    except ValueError as e:
        print(e)
    print("continued on")
    j = int(9.0)

The point of the 'try' block is to encapsulate the code you want to *stop* executing if an exception is raised. If you want code to be run regardless of whether an exception is raised, move it past the try-except.
