Question

I have got the following piece of code, so that while any exception occurs, re-do this loop, instead of jumping to the next loop. Please note the pseudo code here does work as intended:

for cl in range(0, 10):
    try:
        some_function(cl)
    except :
        cl -= 1

My initiative was that once something go wrong, do it again. Obviously, this is not a working idea. So given the assumption that the for loop and range function being used, how to implement the control that I described?

Thanks

You simply need a second loop inside the first to continue trying the function until it works:

for cl in range(0, 10):
    while True:
        try:
            some_function(cl)
        except Exception:
            continue    # try it again
        else:
            break       # exit inner loop, continue to next c1
