Python Modules: Regular Expressions and Collections

Master Python's built-in `re` and `collections` modules to handle advanced text processing and complex data management. This course provides practical experience with regular expression patterns and specialized container datatypes.

Regular Expression Syntax and Patterns
- Identify special characters and construct regular expression patterns.
- Differentiate between greedy and non-greedy repetitions.
The `re` Module Functions and Objects
- Apply `re` module functions like `search`, `match`, `findall`, and `sub` to process strings.
- Extract information using `Match` objects and capturing groups.
Grouping Dictionaries with `ChainMap`
- Explain the purpose and behavior of `ChainMap` for managing multiple mappings.
- Create and manipulate a `ChainMap` to perform cascading dictionary lookups.
Counting and Tallying with `Counter`
- Implement `Counter` objects to tally hashable elements from iterables.
- Calculate the most common elements and combine counts using arithmetic operations.
