Then the example demonstrates initializing an itemgetter with 1 as an argument, which selects the second item in the tuple.Finally, the example shows what would happen if you used itemgetter() with 2 as an argument. Since these tuples only have two index positions, trying to get the third...
The built-indict()constructor creates a Python dictionary. Pass the key-value pairs as the keyword arguments to populate the dictionary. For example: my_dictionary = dict(key1='value1', key2='value2', key3='value3')Copy Use the constructor when initializing a dictionary from various data ...
