New to python here. I've been pulling my hair for hours and still can't figure this out.
I have a list of dictionaries:
[ {'FX0XST001.MID5': '195', 'Name': 'Firmicutes', 'Taxonomy ID': '1239', 'Type': 'phylum'}
{'FX0XST001.MID13': '4929', 'Name': 'Firmicutes', 'Taxonomy ID': '1239','Type': 'phylum'},
{'FX0XST001.MID6': '826', 'Name': 'Firmicutes', 'Taxonomy ID': '1239', 'Type': 'phylum'},
.
.
.
.
{'FX0XST001.MID6': '125', 'Name': 'Acidobacteria', 'Taxonomy ID': '57723', 'Type': 'phylum'}
{'FX0XST001.MID25': '70', 'Name': 'Acidobacteria', 'Taxonomy ID': '57723', 'Type': 'phylum'}
{'FX0XST001.MID40': '40', 'Name': 'Acidobacteria', 'Taxonomy ID': '57723', 'Type': 'phylum'} ]
I want to merge the dictionaries in the list based on their Type, Name, and Taxonomy ID
[ {'FX0XST001.MID5': '195', 'FX0XST001.MID13': '4929', 'FX0XST001.MID6': '826', 'Name': 'Firmicutes', 'Taxonomy ID': '1239', 'Type': 'phylum'}
.

{'FX0XST001.MID6': '125', 'FX0XST001.MID25': '70', 'FX0XST001.MID40': '40', 'Name': 'Acidobacteria', 'Taxonomy ID': '57723', 'Type': 'phylum'}]
I have the data structure setup like this because I need to write the data to CSV using csv.DictWriter later.
Would anyone kindly point me to the right direction?
