To access dictionary elements, you can use the familiar square brackets along with the key to obtain its value.
Example
Following is a simple example −
#!/usr/bin/python
dict = {'Name': 'Zara', 'Age': 7, 'Class': 'First'}
print "dict['Name']: ", dict['Name']
print "dict['Age']: ", dict['Age']Output
When the above code is executed, it produces the following result −
dict['Name']: Zara dict['Age']: 7
If we attempt to access a data item with a key, which is not part of the dictionary, we get an error as follows −
Example
#!/usr/bin/python
dict = {'Name': 'Zara', 'Age': 7, 'Class': 'First'}
print "dict['Alice']: ", dict['Alice']Output
When the above code is executed, it produces the following result −
dict['Alice']: Traceback (most recent call last): File "test.py", line 4, in <module> print "dict['Alice']: ", dict['Alice']; KeyError: 'Alice'
