I saved a list with dict entries to a txt file.
When I try to read it back into python with
data = open("my_saved_data.txt","r")
I just get a huge string which looks like this:
[{key1:"value",key2:"value"},{key1:"value",key2:"value"},{key1:"value",key2:"value"}]
What’s an easy way to get this back in the original format?

What you want is “Convert a String to JSON”, but the type of your file content is not JSON, because the key in JSON should be enclosed in double quotes.
The correct content should like this:
[{"key1":"value","key2":"value"},{"key1":"value","key2":"value"},{"key1":"value","key2":"value"}]
then we can convert it to original format:
with open("my_saved_data.txt","r") as f: data = f.read() print(data) # '[{"key1":"value","key2":"value"},{"key1":"value","key2":"value"},{"key1":"value","key2":"value"}]' import json json.loads(data) #[{'key1': 'value', 'key2': 'value'}, # {'key1': 'value', 'key2': 'value'}, # {'key1': 'value', 'key2': 'value'}]
Please make sure whether your key in str is enclosed or not, if not, we can make it enclosed by:
with open("my_saved_data.txt","r") as f: data = f.read() data.replace('key1','"key1"').replace('key2','"key2"')
