Generic Exception Handling in Python the “Right Way”

Question

Sometimes I find myself in the situation where I want to execute several sequential commands like such:

try:
    foo(a, b)
except Exception, e:
    baz(e)
tr         


        

Answer 1

If they're simple one-line commands, you can wrap them in lambdas:

for cmd in [
    (lambda: foo (a, b)),
    (lambda: bar (c, d)),
]:
    try:
        cmd ()
    except StandardError, e:
        baz (e)

You could wrap that whole thing up in a function, so it looked like this:

ignore_errors (baz, [
    (lambda: foo (a, b)),
    (lambda: bar (c, d)),
])
