Instructions for fixing "E501 Line too long"
For code lines
Break into multiple lines using parentheses or brackets:
python
result = some_very_long_function_name(
parameter1, parameter2, parameter3
)
For single-line strings
Use string concatenation: "ABC" → ("A" "B" "C")
python
message = ("This is a very long string "
"that needs to be broken up")
For long multi-line strings (docstrings)
Add # noqa: E501 AFTER the ending """. NEVER add it inside the docstring.
python
def example_function():
"""This is a very long docstring that exceeds the line length limit.""" # noqa: E501
pass
What NOT to do
- •Do not add
# noqa: E501inside docstrings or multi-line strings - •Do not break strings in the middle of words
- •Do not sacrifice code readability for line length compliance
