In Python 3.5 or greater:

z = {**x, **y}

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 now:

z = merge_two_dicts(x, y)

This way you can merge dictionaries in Python. Hope it helps. Please post if there are any other queries.
