BufferError — Expert Playground
Raised when a buffer-related operation fails
Python Playground
# Exception groups (Python 3.11+)
import sys
print(f"Python {sys.version}")
# Exception hierarchy inspection
print(f"BufferError MRO:")
for cls in BufferError.__mro__:
print(f" {cls.__name__}")
# Exception attributes
try:
raise BufferError("buffer error")
except BufferError as e:
print(f"\nException attributes:")
print(f" args: {e.args}")
print(f" __traceback__: {type(e.__traceback__)}")
# Traceback manipulation
import traceback
tb_lines = traceback.format_exception(type(e), e, e.__traceback__)
print(f" Traceback lines: {len(tb_lines)}")
