I currently have a list and woulr like to store the contents into a 
text fiel whihc I can read back ... 

For example:
a = ['a','b','c','d']
#do something like
fd = open('txt.txt','w')
fd.write(a)
Traceback (innermost last):
  File "<stdin>", line 1, in ?
TypeError: read-only buffer, list

What to do??
And I can't use pickle ...

later on I would like to read it back...

fd = open('txt.txt','r')

iniInfo = fd.readlines()
b=[]
b = iniInfo[0]
# copy list contents into c
map(c.append,b)

I think this also not work right 
?
Can someone kindly tell me how to do write and read a list to a file?

Thanks
