vb2Py - Do ... Loop

Contents of this page:

Different forms:

General

All variations of VB's Do ... Loop construct are converted to an equivalent Python while block. Preconditions are converted to the equivalent condition in the while statement itself, whereas post-conditions are implemented using an if ...: break . Exit's from the loop are also implemented using break . Until conditions (pre or post) are implemented by negating the condition itself but do not affect the structure.

Default Conversion

            break
        if not (Condition):
            break

Do Until ... Loop

VBPython

Do Until Condition
    Val = Val + 1
    If SomeCondition Then Exit Do
