Hi all,
I'm looking for some structure advice. I'm writing something that
currently looks like the following:
try:
<short amount of code that may raise a KeyError>
except KeyError:
<error handler>
else:
<nontrivial amount of code>
This is working fine. However, I now want to add a call to a function
in the `else' part that may raise an exception, say a ValueError.
If your error handler terminates the function (which is usually the case
when using the else clause), you can just skip the else statement, ie:
try:
<short amount of code that may raise a KeyError>
except KeyError:
<error handler with early exit>
<nontrivial amount of code>
Then adding one or more try/except is just trivial.
So I
was hoping to do something like the following:
try:
<short amount of code that may raise a KeyError>
except KeyError:
<error handler>
else:
<nontrivial amount of code>
except ValueError:
<error handler>
However, this isn't allowed in Python.
Nope. But this is legal:
try:
<short amount of code that may raise a KeyError>
except KeyError:
<error handler>
else:
try:
<nontrivial amount of code>
except ValueError:
<error handler>
An obvious way round this is to move the `else' clause into the `try'
"obvious" but not necessarily the best thing to do.
