How do I sort a list of dictionaries by a value of the dictionary?

Question

I have a list of dictionaries and want each item to be sorted by a specific value.

Take into consideration the list:

[{\'name\':\'Homer\', \'age\':39},

Here is the alternative general solution - it sorts elements of a dict by keys and values.

The advantage of it - no need to specify keys, and it would still work if some keys are missing in some of dictionaries.

def sort_key_func(item):
    """ Helper function used to sort list of dicts

    :param item: dict
    :return: sorted list of tuples (k, v)
    """
    pairs = []
    for k, v in item.items():
        pairs.append((k, v))
    return sorted(pairs)
sorted(A, key=sort_key_func)
