Kwargs

Kwargs

# Python 3.5+ allows passing multiple sets
# of keyword arguments ("kwargs") to a
# function within a single call, using
# the "" syntax:

def process_data(a, b, c, d):
print(a, b, c, d)

x = {'a': 1, 'b': 2}
y = {'c': 3, 'd': 4}

process_data(**x, **y)
# >>> 1 2 3 4

process_data(**x, c=23, d=42)
# >>> 1 2 23 42
