Sum of values for specific key in a list of dictionaries python

I've got a list of dictionaries:

[({'symbol':symbol, 'name':name, 'shares_total':shares_total, 'price':price, 'holding_value':holding_value})
 ({'symbol':symbol, 'name':name, 'shares_total':shares_total, 'price':price, 'holding_value':holding_value})
 etc.
]

I want to introduce a variable holdings_total which is the sum of values for all "holding_value" keys in a list of dictionaries.

I believe there is some succinct method, but cannot figure it out.

Could someone help?

Thanks!

#lst = list of dicts

sum_hold = sum(d.get('holding_value', 0) for d in lst)

In case the dict does not have the holding_value key
