Chapter 2. Text Management

In this chapter, we will cover the following recipes:

  • Pattern matching—regular expressions are not the only way to parse patterns; Python provides easier and just as powerful tools to parse patterns
  • Text similarity—detecting how two similar strings in a performing way can be hard but Python has some easy-to-use built-in tools
  • Text suggestion—Python looks for the most similar one to suggest to the user the right spelling
  • Templating—when generating text, templating is the easiest way to define the rules
  • Splitting strings preserving spaces—splitting on empty spaces can be easy, but gets harder when you want to preserve some spaces
  • Cleanup text—removes any punctuation or odd character from text
  • Normalizing text—when working with international text, it's often convenient to avoid having to cope with special characters and misspelling of words
  • Aligning text—when outputting text, properly aligning it greatly increases readability
