format_exception#

astropy.utils.misc.format_exception(msg, *args, **kwargs)[source]#

Deprecated since version 7.0: The format_exception function is deprecated and may be removed in a future version.

Fill in information about the exception that occurred.

Given an exception message string, uses new-style formatting arguments {filename}, {lineno}, {func} and/or {text} to fill in information about the exception that occurred. For example:

try:

1/0

except:
raise ZeroDivisionError(
format_except(‘A divide by zero occurred in {filename} at ‘

‘line {lineno} of function {func}.’))

Any additional positional or keyword arguments passed to this function are also used to format the message.

Note

This uses sys.exc_info to gather up the information needed to fill in the formatting arguments. Since sys.exc_info is not carried outside a handled exception, it’s not wise to use this outside of an except clause - if it is, this will substitute ‘<unknown>’ for the 4 formatting arguments.
