Questions:

1.  How are you determining that the output is clear?  I don't know
what you mean by "output is clear".


2.  Does your program close() the file that it is writing to?  See:

    https://docs.python.org/2/library/stdtypes.html#file.write
    https://docs.python.org/2/library/stdtypes.html#file.close

as to why this may be important.


3.  Your problem description says:

    i need to export to file all stings which start from "Name"

but the code here:

    for word in line.split():
        if word in keywords:
            ...

is doing much more than what is required.  It is checking whether
"Name" shows up anywhere on the line, not just as part of the name of
the left-hand-side key.  Is that ok?
