Getting String Objects Instead of Unicode from JSON (Python 2)
When parsing JSON from ASCII-encoded text files in Python 2, the default behavior is to represent string values as Unicode objects. This can pose a problem when working with libraries that only accept string objects.
Fortunately, there are several ways to obtain string objects instead of Unicode objects:
Using PyYAML
PyYAML is a Python library for parsing YAML, which is a superset of JSON. It provides a convenient way to get string objects while preserving the JSON structure:
<code class="python">import yaml json_string = '["a", "b"]' data = yaml.safe_load(json_string) # Returns a list of strings</code>
Note: This method only works for ASCII-encoded data.
Converting Unicode to String Objects
If the data is Unicode-encoded, you can use a conversion function to convert the Unicode strings to regular strings:
<code class="python">def unicode_to_string(obj):
if isinstance(obj, basestring):
return obj.encode('utf-8')
elif isinstance(obj, dict):
return dict((unicode_to_string(k), unicode_to_string(v)) for k, v in obj.iteritems())
elif isinstance(obj, list):
return [unicode_to_string(v) for v in obj]
else:
return obj
# Usage:
json_string = '["\u00e1", "\u00e9"]'
data = json.loads(json_string)
converted_data = unicode_to_string(data) # Converts Unicode strings to strings</code>Using an Object Hook
You can also use an object hook to convert Unicode strings to strings during serialization:
<code class="python">import json
def object_hook(obj):
if isinstance(obj, unicode):
return obj.encode('utf-8')
return obj
# Usage:
json_string = '["a", "b"]'
data = json.loads(json_string, object_hook=object_hook) # Converts Unicode strings to strings during deserialization</code>The above is the detailed content of How to Get String Objects Instead of Unicode from JSON in Python 2?.
