Convert Python to Groovy - Nested Json

I am working on implementing a workflow using Nextflow. Nextflow uses groovy as it's base language and then each process can use any programming language independently. I am essentially a Python programmer, so the code I've written is in Python. And am having a little trouble converting the language.
data = {
"a" : "A",
"b" : "B",
"c" : {
"somename":{
"z" : "Z",
"y" : "Y",
"params" :{
"minimum": "3000",
"ignore": "60",
"maximum_A": "2500",
"maximum_B": "500"
}
},
"somename2":{
"z" : "Z",
"y" : "Y",
"params" :{
"minimum": "3000",
"ignore": "60",
"maximum_A": "2500",
"maximum_B": "500"
}
}
}
}
CNS_PARAM_LIST = []
my_dict = {}
for each in data["c"]:
for k, v in data["c"][each].get('params', {}).items():
CNS_PARAM_LIST.extend([k, str(v)])
my_dict[each] = CNS_PARAM_LIST
print(my_dict)
Basically, I have a JSON (data) and I need to make a dictionary from some nested fields. The output for the above code is:
{'somename': ['minimum', '3000', 'ignore', '60', 'maximum_A', '2500', 'maximum_B', '500', 'minimum', '3000', 'ignore', '60', 'maximum_A', '2500', 'maximum_B', '500'], 'somename2': ['minimum', '3000', 'ignore', '60', 'maximum_A', '2500', 'maximum_B', '500', 'minimum', '3000', 'ignore', '60', 'maximum_A', '2500', 'maximum_B', '500']}
Simply, make somename and somename2 the keys, and make params the values.
Any groovy coder that could crack this in 1/100th the time I can? I'm sure there is also some way to make this code more efficient, any ideas are welcome!

I guess you just misspelled when duplicated keys for each somename
the first diff in groovy is how to declare a map (dictionary in python)
my_dict = [:]
more about groovy collections you can find here:
the code for your case:
def data = [
"a" : "A",
"b" : "B",
"c" : [
"somename":[
"z" : "Z",
"y" : "Y",
"params" :[
"minimum": "3000",
"ignore": "60",
"maximum_A": "2500",
"maximum_B": "500"
]
],
"somename2":[
"z" : "Z",
"y" : "Y",
"params" :[
"minimum": "3000",
"ignore": "60",
"maximum_A": "2500",
"maximum_B": "500"
]
]
]
]
def my_dict = data.c.collectEntries{k,v-> [k,v.params] }
println my_dict
//if you want to print it as json:
println groovy.json.JsonOutput.toJson(my_dict)
i'm using collectEntries method on Map object
you could find other methods for Map in GDK documentation: groovy Map just google gdk map
as soon as groovy Map extends java Map check main methods in javadoc: java Map
