Parse Logs with Python | Dataford Interview Questions

Can you write a Python script to parse a text file and extract specific log patterns?

Implement parse_log_patterns(text, patterns), where text is the file content and patterns maps pattern names to valid regular expressions. Return a dictionary mapping each name to matching lines in their original order. A line belongs to every pattern it matches.

Input and Output

text: string. patterns: dictionary of string names to regex strings. Return dict[str, list[str]]; omit no pattern names, even when there are no matches.

Constraints

0 <= number of input lines <= 1,000
0 <= number of patterns <= 100
Pattern names are strings and are unique
All regular-expression strings are valid
Matching is case-sensitive
Return each input pattern name, including names with no matches
