# Basic syntax:
your_dictionary.update({'keys':23, 'to':42, 'update':17})
# Example usage:
your_dictionary = {'keys':0, 'to':0}
your_dictionary.update({'keys':23, 'to':42, 'update':17})
print(your_dictionary)
--> {'keys': 23, 'to': 42, 'update': 17}
# Note, along with updating existing key values, the .update() method
# adds keys to the dictionary if they aren't present
d = {'k1': 1, 'k2': 2}
d.update(k1=100, k3=3, k4=4)
print(d)
# {'k1': 100, 'k2': 2, 'k3': 3, 'k4': 4}
