Errata for Dive Into Python 5.4
5. Objects and Object-Orientation
5.2 Importing Modules Using from module import
Para 2: Notice the words in bold. The code shows the imported object is class UserDict, not the attributes and methods of the imported module types.BR Here is the basic from module import syntax:BR from UserDict import UserDictBR This is similar to the import module syntax that you know and love, but with an important difference: the attributes and methods of the imported module types are imported directly into the local namespace, so they are available directly, without qualification by module name.BR
7. Regular Expressions
7.4 Using the {n,m} Syntax
Example 7.7: The rule that M cannot repeat for more than three times is broken. Relative bugs are found in this section and the following section.
12. SOAP Web Services
12.6 Introspecting SOAP Web Services with WSDL
Example 12.8: Notice that there is one more ) on the second line.
>>> from SOAPpy import WSDL >>> wsdlFile = 'http://www.xmethods.net/sd/2001/TemperatureService.wsdl') >>> server = WSDL.Proxy(wsdlFile) >>> server.methods.keys() [u'getTemp']
16. Functional Programming
16.3 Filtering lists revisited
Example 16.7, (1): odd uses the built-in mod function "%" to return True if n is odd and False if n is even.BR
The True and False should be 1 and 0.
18. Performance Tuning
A great bug
The "best result so far" in stage2 is 1e, but the text said it is 1c. The code is all right.
The test result for 2c differs too much in stage 2 and in stage 3; either of them is wrong or should be abandoned.
There are many conflictings between the text and the test result. Please refer to [../xe/soundexbug], there is a picture stage0.jpg showing the conflictings. I adopted the result in stage 2 for 2c.BR The black arrow shows the relationship according the text ("a -> b" means "a is slower than b"). The blue and red arrows show the conflictings. The numbers beside them stands for the test cases(1. Woo, 2. Pilgrim, 3. Flingjingwaller). Blue arrows mean that the two data differ little, so the conflicting may be ommited; and red arrows mean that the performance relationship between the two programs are totally on the opposite.
