swampy.TurtleWorld not working in python 3.4 -


i m learning python using thinkpython book, using python 3.4 , anaconda ide. part of need continue install module called swampy. installed using pip, worked well. importing module worked tkinter, can't use of functions in module. checked lib folder, swampy there , functions in swampy folder. can't figure out why not working. please need help. if question isn't clear enough please let me know. have included code tried run , error message each time try running it

the code try run (page 29, chapter 4 of think python version python 3.4)

import tkinter import swampy world = swampy.turtleworld bob = turtle() print(bob) wait_for_user()

error message got

traceback (most recent call last):   file "<stdin>", line 1, in <module>   file "c:\users\mbaka1\anaconda3\lib\site-packages\spyderlib\widgets\externalshell\sitecustomize.py", line 682, in runfile     execfile(filename, namespace)   file "c:\users\mbaka1\anaconda3\lib\site-packages\spyderlib\widgets\externalshell\sitecustomize.py", line 85, in execfile     exec(compile(open(filename, 'rb').read(), filename, 'exec'), namespace)   file "c:/users/mbaka1/documents/python scripts/test.py", line 28, in <module>     world = swampy.turtleworld attributeerror: 'module' object has no attribute 'turtleworld'

the book shows these directions if you've downloaded source code:

from turtleworld import * world = turtleworld() bob = turtle() print(bob) wait_for_user()

if want run code after installing pip, should work:

from swampy.turtleworld import * world = turtleworld() bob = turtle() print(bob) wait_for_user()

the reason you're doing isn't working because turtleworld module within swampy package, contains functions same name, i.e. turleworld. when import swampy , try calling swampy.turtleworld you're trying call module rather function.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
