print two dimensional list

Question

I have a list, in which is another list and I want to doc.write(a)

a = [[1, 2, \"hello\"],
     [3, 5, \"hi There\"],
     [5,7,\"I don\'t know\"]]
         


        

Answer 1

It's difficult for me to be sure, because your question is too short, but it seems to me that you are in a XY problem, that is to say :
you ask a question about a Y problem that you think of as being the one that needs to be solved to goes out of an uphill X problem. But your real problem is that you think that the Y problem is the way to answer to the real problem X AND that you present here only the Y problem.
Writing that, I only paraphrase what is said here: XY problem

If I am right, my opinion is that you will have a better way to solve your real X problem using one of the following tools, that allow to serialize an object and to record the serialized object in a file:

pickle

marshal

shelve

I won't paraphrase and repeat all is the docs on these tools, read them.

.

If i am wrong and that you really just want to write an object under the form of a string representation, you can also do:

from pprint import pformat

a = [[1, 2, "hello"],
     [3, 5, "hi There"],
     [5,7,"I don't know"]]

with open('doc.txt','w') as f:
    f.write(pformat(a,width=12))
