Regular expression for int and double

Question

I am trying to find the regular expression for getting the Error value from the following string:

{'Sample': '#it{House}', 'Yield': 0.0012267869301467726, 'Error': 0}

I tried "'Error': (\d+.\d+)" but I have the case that the Error can be either an integer (like 0) or a double value like 0.992. I checked many cases but still cannot find the regular expression.

If it is yaml, then use the yaml module so that you get the variables as is. That looks like json though, so maybe the json module would be better — user1558604, Jul 26 '20 at 15:23
JSON is YAML, though the standard library has the `json` module but no module for YAML. — chepner, Jul 26 '20 at 15:25
But Yaml isn't json. That string isn't json because json only uses double quotes . — erik258, Jul 26 '20 at 15:27

If that data is indeed formatted with yaml, you can read it with the yaml module (which is not part of the default distribution of python):

$ python -c 'import yaml,sys; print(yaml.load(sys.stdin.read())["Yield"])' <<<"{'Sample': '#it{House}', 'Yield': 0.0012267869301467726, 'Error': 0}"
0.00122678693015
