No attribute Rule

[huuhuannt1998]

I have trying the following example:

import rule_engine
import datetime

comics = [
  {
    'title': 'Batman',
    'publisher': 'DC',
    'issue': 89,
    'released': datetime.date(2020, 4, 28)
  },
  {
    'title': 'Flash',
    'publisher': 'DC',
    'issue': 753,
    'released': datetime.date(2020, 5, 5)
  },
  {
    'title': 'Captain Marvel',
    'publisher': 'Marvel',
    'issue': 18,
    'released': datetime.date(2020, 5, 6)
  }
]

rule = rule_engine.Rule(
  # match books published by DC
  'publisher == "DC"'
)

# check if the first object matches
print(rule.matches(comics[0])) # => True

# filter the iterable "comics" and return matching objects
print(rule.filter(comics)) # => <generator object Rule.filter at 0x7f2bdafbe650>

I got this error "AttributeError: partially initialized module 'rule_engine' has no attribute 'Rule' (most likely due to a circular import)". How do I get this fixed?

I can't reproduce that error. You're not naming your Python source file rule_engine.py are you?

That is the name of my python file.

Try changing it to anything else. You're defining the rule_engine module yourself and not defining the Rule class. Rename it to test.py or something else.

It works. Thanks for your help.
