The Black code style guide emphasizes consistency, readability, and minimizing diffs in Python code. Key formatting rules include ignoring previous formatting, preferring double quotes, adding trailing commas, and wrapping lines to fit within 88 characters. Black standardizes whitespace usage, avoids unnecessary vertical space, and ensures uniform handling of parentheses, comments, and numeric literals. The formatter also aligns with PEP 8 and PEP 257 standards, and provides options to adjust line length and skip string normalization for specific projects.
