Validation for nested data structures

Installing

pip install valida

A simple example

from valida import Data, Value, Rule

# Define some data that we want to validate:
my_data = Data({'A': 1, 'B': [1, 2, 3], 'C': {'c1': 8.2, 'c2': 'hello'}})

# Define a rule as a path within the data and a condition at that path:
rule = Rule(
  path=('C', 'c2'),
  condition=Value.dtype.equal_to(str),
)

# Test the rule
rule.test(my_data).is_valid # `True` => The rule tested successfully
