How do I convert a Python dictionary to a MATLAB type?

21 次查看(过去 30 天)
I have a Python dictionary in MATLAB which I would like to convert to a MATLAB type, but I am having trouble with the method used in this document page:
  • https://www.mathworks.com/help/releases/R2020a/matlab/matlab_external/use-python-dict-type-in-matlab.html
I believe the problem is converting to a MATLAB "struct." The data in my dictionary does not conform to struct naming conventions listed here:

While MATLAB structs have strict naming conventions for their data, there are other MATLAB data types which a dictionary can be converted into.
If we already have our Python environment loaded (which can be done manually with the MATLAB "pyenv" function), we can create a Python dictionary directly in MATLAB with the following command:
dict = py.dict(pyargs('2020-1-1 10:00:00.1', 'Value_1', '2020-1-2 12:10:00.5', 'Value_2'))
We can now convert this Python dictionary into a MATLAB map by iterating over the dictionary:
M = containers.Map; for raw_key = py.list(keys(dict)) key = raw_key{1}; value = dict{key}; M(string(key)) = string(value); end
Alternatively, we can convert the dictionary into a MATLAB table:
T = table; for raw_key = py.list(keys(dict)) key = raw_key{1}; value = dict{key}; T2 = table(string(value), 'VariableNames', [string(key)]); T = [T T2]; end
Note that this dictionary could not be converted into a MATLAB struct because the keys of the dictionary do not conform to struct naming conventions, since they do not start with a letter.
