.
This module provides access to symbolic error codes for OSError exception. A particular inventory of codes depends on MicroPython port.
Constants¶
-
EEXIST, EAGAIN, etc.
Error codes, based on ANSI C/POSIX standard. All error codes start with “E”. As mentioned above, inventory of the codes depends on MicroPython port. Errors are usually accessible as
exc.args[0]
whereexc
is an instance of OSError. Usage example:try: uos.mkdir("my_dir") except OSError as exc: if exc.args[0] == uerrno.EEXIST: print("Directory already exists")
-
uerrno.
errorcode
¶ Dictionary mapping numeric error codes to strings with symbolic error code (see above):
>>> print(uerrno.errorcode[uerrno.EEXIST]) EEXIST
