You never imported string; so you have the name error.
Furthermore the [11] is alist; but you need to give a integer as
argument here.

But there is no need to import string.

First there should be a lot of documentation coming with your Python
system.  Then a lot of docu can be read interactively. Eg. if you wanted
to know which methods strings have you just type:

>>> s = ""
>>> dir(s)
['__add__', '__class__', '__contains__', '__delattr__', '__doc__', '__eq__', '__ge__', '__getattribute__', '__getitem__', '__getnewargs__', '__getslice__', '__gt__', '__hash__', '__init__', '__le__', '__len__', '__lt__', '__mod__', '__mul__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__rmod__', '__rmul__', '__setattr__', '__str__', 'capitalize', 'center', 'count', 'decode', 'encode', 'endswith', 'expandtabs', 'find', 'index', 'isalnum', 'isalpha', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper', 'join', 'ljust', 'lower', 'lstrip', 'replace', 'rfind', 'rindex', 'rjust', 'rstrip', 'split', 'splitlines', 'startswith', 'strip', 'swapcase', 'title', 'translate', 'upper', 'zfill']
>>> 

The first line created a string, the second line shows me all its
methods.  The same works for every object.  Also try help()

>>> help()

Welcome to Python 2.3!  This is the online help utility.

If this is your first time using Python, you should definitely check out
the tutorial on the Internet at http://www.python.org/doc/tut/.

Enter the name of any module, keyword, or topic to get help on writing
Python programs and using Python modules.  To quit this help utility and
return to the interpreter, just type "quit".

To get a list of available modules, keywords, or topics, type "modules",
"keywords", or "topics".  Each module also comes with a one-line summary
of what it does; to list the modules whose summaries contain a given word
such as "spam", type "modules spam".

You can read a lot there.

But back to your problem.

I assume you have a relatively current version of Python so your code
can be written a bit simpler and IMO easier to read.

f=open ("book2.txt")
for line in f:
  print line
  L = line.split(",", 11)
  PlayIt.SetFieldContent ("SY012M1", "art-nr", L[0])
  PlayIt.PlayContent ("{CSB SY012M1|art-nr}{Enter}")
  PlayIt.SetFieldContent ("SY012ADM1", "001bez",  L[1])
  PlayIt.SetFieldContent ("SY012ADM1", "005agr",  L[2])
  PlayIt.SetFieldContent ("SY012ADM1", "006agr",  L[3])
  PlayIt.SetFieldContent ("SY012ADM1", "009kst",  L[4])
  PlayIt.SetFieldContent ("SY012EHM1", "005laeh", L[5])
  PlayIt.SetFieldContent ("SY012EHM1", "006lauf", L[6])
  PlayIt.SetFieldContent ("SY012EHM1", "011vkuf", L[7])
  PlayIt.SetFieldContent ("SY012SDM1", "012fest", L[8])
  PlayIt.SetFieldContent ("SY012PRM1", "001tpr",  L[9])
  PlayIt.SetFieldContent ("SY012PRM1", "002wpr",  L[10])
  PlayIt.SetFieldContent ("SY012PRM1", "003plpr", L[11])
  PlayIt.PlayContent ("{CSB SY012M1|art-nr}{F2}")

f.close()

(I replaced your l with L since IMO a single smallcaps l is hard to
distinguish from a 1.)
