Not tested, but I suspect you could do something like this. Depending on the scope of the variable you'd have to change it, but I think you'll get the idea
try:
something
except Exception as e:
variable_to_make_exception = e
.....later on use variable
an example of using this way of handling errors:
errors = {}
try:
print(foo)
except Exception as e:
errors['foo'] = e
try:
print(bar)
except Exception as e:
errors['bar'] = e
print(errors)
raise errors['foo']
output..
{'foo': NameError("name 'foo' is not defined",), 'bar': NameError("name 'bar' is not defined",)}
Traceback (most recent call last):
