Answer 1

将for循环中的output.write()行更改为此：

output.write("{0} {1} {2}\n".format(str(key), str(value[0]), str(value[1]))

Answer 2

A little more pythonic with itertools.chain and join : Also note the conversion to ints.

mydic={
    "Deepu":(794.0, 586.0),
    "Facebook":(800.0, 329.0),
    "LinkedIn":(789.0, 768.0),
    "Google+":(502.0, 671.0),
    "Viber":(716.0, 559.0),
    "GoogleTalk":(1093.0, 678.0),
    "Plus2":(1072.0, 239.0),
    "Btech":(534.0, 253.0),
    "Mtech":(788.0, 136.0)
}

from itertools import chain
print "\n".join(" ".join(chain([key],[str(int(number)) for number in value])) for key,value in mydic.items())

Output:

Viber 716 559
Google+ 502 671
Facebook 800 329
LinkedIn 789 768
Plus2 1072 239
Mtech 788 136
Btech 534 253
Deepu 794 586
GoogleTalk 1093 678
