Is your data meeting all your expecations

data_expectations

Is your data meeting your expectations?

---

Data Expectations is in Alpha - interface and usage patterns are being stablized

A delarative approach to asserting qualities of your datasets. Instead of tests like is_sorted to determine if a column is ordered, the expectation is column_values_are_increasing. Most of the time you don't need to know how it got like that, you are only interested what the data looks like.

Expectations can be used alongside, or in place of a schema validator, however they are not intended to perform validation of the data in a dataset, not just the structure of a table.

Expectations

• expect_column_to_exist
• expect_column_names_to_match_set
• expect_column_values_to_not_be_null
• expect_column_values_to_be_of_type
• expect_column_values_to_be_in_type_list
• expect_column_values_to_be_between
• expect_column_values_to_be_increasing
• expect_column_values_to_be_decreasing
• expect_column_values_to_be_in_set
• expect_column_values_to_match_regex
• expect_column_values_to_match_like
• expect_column_values_length_to_be_be
• expect_column_values_length_to_be_between

Install

pip install data_expectations

if data doesn't match, I'm not angry, I'm just disappointed.
