CODE EXAMPLE FOR PYTHON

merge two dict python

For dictionaries x and y, their shallowly-merged dictionary z takes values from y, replacing those from x.

In Python 3.9.0 or greater (released 17 October 2020, PEP-584, discussed here):

z = x | y
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 keys and values of x
    z.update(y)    # modifies z with keys and values of y
    return z
and now:

z = merge_two_dicts(x, y)
