How do I add keys to a dictionary in a list of dictionaries?

Question

Simple question that I can't seem to find an answer to:

How do I add/append a key to a dictionary that resides in a list of dictionaries?

---

Given the list below:

list = [{'key-1': 'value-1', 'key-2': 'value-2'}, {'key-A': 'value-A'}]

I want to add 'key-B": "value-B' in the second dictionary for the result to be:

list = [{'key-1': 'value-1', 'key-2': 'value-2'}, 
        {'key-A': 'value-A', 'key-B': 'value-B'}]

I thought I could just .update or .append to it but, no such luck.

Any assistance with this is greatly appreciated.

Answer 1

just do this.

list[1]['key-B'] = 'value-B'

OUTPUT

print(list)
[{'key-2': 'value-2', 'key-1': 'value-1'}, {'key-B': 'value-B', 'key-A': 'value-A'}]
