Python Hash Table 

#Python demonstrate hashtable usage

#Python dictionary

items1 = dict({"key1": 1, "key2": "two", "key3": 3})


print(items1) #print all items


#Python empty dictionary

items2 = {}

items2["key1"] = 1

items2["key2"] = 2

items2["key3"] = 3

print(items2)

#Python if key not in dictionary

#uncomment to run i.e remove the hashtag in front of print

#print(items2["key6"])


#Python dictionary update

items2["key2"] = "two"

print(items2)


#Python iterate dictionary

for key, value in items2.items():

    print("Key: ", key, "Value: ", value)


-------------------------------------------------------------------------------




#Output


{'key1': 1, 'key2': 'two', 'key3': 3}
{'key1': 1, 'key2': 2, 'key3': 3}
{'key1': 1, 'key2': 'two', 'key3': 3}
Key:  key1 Value:  1
Key:  key2 Value:  two
Key:  key3 Value:  3
