Reorder dictonaries within a list

May 22, 2022

I have a list containing dictionaries that look like this:

[{'isin': 'IE000000001', 'MP': 'B', 'market_share': 30}, {'isin': 'IE000000002', 'MP': 'C', 'market_share': 50}, {'isin': 'IE000000003', 'MP': 'D', 'market_share': 70}]

I would like to reorder the dictionaries in my list based on their ‘market share’ so that I would end up with something like that

[{'isin': 'IE000000003', 'MP': 'D', 'market_share': 70}, {'isin': 'IE000000002', 'MP': 'C', 'market_share': 50},{'isin': 'IE000000001', 'MP': 'B', 'market_share': 30}]

Do you have any recommendations?

>Solution :

You don’t need pandas for this.

# sort the list by market_share
my_data.sort(key=lambda x:x['market_share'], reverse=True)
my_data
[{'isin': 'IE000000003', 'MP': 'D', 'market_share': 70},
 {'isin': 'IE000000002', 'MP': 'C', 'market_share': 50},
 {'isin': 'IE000000001', 'MP': 'B', 'market_share': 30}]
