hi, I only know a little python to play with klipper but until now I found what I needed now I need a dictionary to store a list of keys and values and like to update the items by a macro here I have my dictionary [gcode_macro _test_variables] variable_feature_hops: {“feature1”: 1.0, “feature2”:…

For that, I will refer you to this excellent post by @garethky : [image] Macro Creation Tutorial Macros something to add to the tutorial: The SET_GCODE_VARIABLE and SAVE_VARIABLE commands in klipper require that you pass them Python literals. Simple strings and numbers are…

Try something like: SET_GCODE_VARIABLE MACRO=_test_variables VARIABLE=feature_hops VALUE='{"mykey": 123.4}' -Kevin

thanks, result sadly is Error loading template ‘gcode_macro _set_feature_retraction_zhop:gcode’: jinja2.exceptions.TemplateSyntaxError: expected token ‘end of print statement’, got ‘:’ same result without ‘’

{% set dummy = feature_hops.__setitem__(feature, distance) %}

thanks @theophile this really works to add an item to the dict :slight_smile: now how do I write the new dictionary back to the other macro’s variable? SET_GCODE_VARIABLE MACRO=_retraction_variables VARIABLE=feature_hops VALUE={feature_hops} returns Malformed command ‘SET_GCODE_VARIABLE MACRO=_r…

awsome it works _set_feature_retraction_zhop feature=lala distance=5 feature_retraction_zhops: {‘featureName’: 1.0, ‘lala’: 5.0} _set_feature_retraction_zhop feature=lulu distance=3 feature_retraction_zhops: {‘featureName’: 1.0, ‘lala’: 5.0, ‘lulu’: 3.0} using getitem to get an item is the be…

Yes, __getitem__ works well, and has the benefit of returning None instead of an error if the specified key isn’t in the dictionary for some reason. I don’t think it’s any slower than trying to access the value directly.
