I need to merge multiple dictionaries, here\'s what I have for instance:

Answer 1

The following function merges b into a.

def mergedicts(a, b):
    for key in b:
        if isinstance(a.get(key), dict) or isinstance(b.get(key), dict):
            mergedicts(a[key], b[key])
        else:
            a[key] = b[key]
    return a
