Python-如何更新列表索引

Question

Pseudo code:

data = []
data.append({'name': 'John', 'age': '37'})
data.append({'name': 'Joe', 'age': '25'})

Here I do some calculations and I want to update data[0], in order to get:

data[0] = {'name': 'John', 'age': '37', 'country': 'USA'}

How can I update that first index of list?

Answer 1

Like:

data[0]['country'] = 'USA' # if you want to set value of country only

or

data[0] = {'name': 'John', 'age': '37', 'country': 'USA'} # if you want to update whole dictionary
