This code defines two functions, `dedent` and `dedent_textwrap`. The `dedent` function manually calculates the minimum indentation level and removes it from each line. The `dedent_textwrap` function uses the `textwrap.dedent` function from the Python standard library to achieve the same result. Both functions filter out blank lines when calculating the minimum indentation level. The example usage demonstrates how to use these functions to de-dent a string of Python code.

Substring Evaluation

Testing if the previous output contains the string All tests passed: True
