Python - print tab delimited two-word set

Question

I have a set of words such as this: ``` mike dc car dc george dc jerry dc ``` Each word, `mike dc george dc` is separated by a space. How can I create a two-word set and separate the two-word set by a tab? I would like to print it to the standard output `stdout`. EDIT I tried using this: `print '	'.join(hypoth)`, but it doesn't really cut it. All the words here are just tab delimited. I would ideally like the first two words separated by a space and each two word-set tab delimited.

Accepted Answer

Assuming you have

```
two_word_sets = ["mike dc", "car dc", "george dc", "jerry dc"]
```

use

```
print "	".join(two_word_sets)
```

or, for Python 3:

```
print("	".join(two_word_sets))
```

to print the tab-separated list to stdout.

If you only have

```
mystr = "mike dc car dc george dc jerry dc"
```

you can calculate a as follows:

```
words = mystr.split()
two_word_sets = [" ".join(tup) for tup in zip(words[::2], words[1::2])]
```

This might look a bit complicated, but note that `zip(a_proto[::2], a_proto[1::2])` is just `[('mike', 'dc'), ('car', 'dc'), ('george', 'dc'), ('jerry', 'dc')]`. The rest of the list comprehension joins these together with a space.

Note that for very long lists/input strings you would use `izip` from [`itertools`], because `zip` actually creates a list of tuples whereas `izip` returns a generator.
