phone that evil

Key 5 is clickable,

<methodResponse>
  <fault>
    <value>
      <struct>
        <member>
          <name>faultCode</name>
          <value>

              XML error: Invalid document end at line 1, column 1
            </string>
          </value>
        </member>
      </struct>
    </value>
  </fault>
</methodResponse>

Solution

We can use xmlrpc module to talk to it:

>>> import xmlrpc.client
>>> conn = xmlrpc.client.ServerProxy("http://www.pythonchallenge.com/pc/phonebook.php")
>>> conn
<ServerProxy for www.pythonchallenge.com/pc/phonebook.php>
>>> conn.system.listMethods()
['phone', 'system.listMethods', 'system.methodHelp', 'system.methodSignature', 'system.multicall', 'system.getCapabilities']

phone seems to be the method we should call. Get more info on how to use it:

>>> conn.system.methodHelp("phone")
'Returns the phone of a person'
>>> conn.system.methodSignature("phone")
[['string', 'string']]

So it takes a string and returns a string, the input should be the name and the output should be the number:

>>> conn.phone("Bert")
'555-ITALY'

If you do not know, 555 basically means "fake phone numbers" in US... The key is "italy".

Put Everything Together

import xmlrpc.client

conn = xmlrpc.client.ServerProxy("http://www.pythonchallenge.com/pc/phonebook.php")
print(conn.phone("Bert"))
