python에서 두개의 dictionary를 하나로 합치는 방법

How can I merge two Python dictionaries in a single expression?

For dictionaries x and y, z becomes a merged dictionary with values from y replacing those from x.

In Python 3.5 or greater, :

z = {**x, **y}
w = {'foo': 'bar', 'baz': 'qux', **y}  # merge a dict with literal values

In Python 2, (or 3.4 or lower) write a function:

def merge_two_dicts(x, y):
    z = x.copy()   # start with x's keys and values
    z.update(y)    # modifies z with y's keys and values & returns None
    return z

and

z = merge_two_dicts(x, y)
