Given a list of strings, how would you iterpolate a multi-character string in front of each element?
For example, given:
>>> k = ['the quick', 'brown fox', 'jumps over', 'the lazy', 'dog']
The objective is to get:
['-c', 'the quick', '-c', 'brown fox', '-c', 'jumps over', '-c', 'the lazy', '-c', 'dog']
Of course, the naive solution would be to compose a new list by iterate over the original list:
>>> result = 
>>> for i in k:
Alternatively, you could take advantage of the
>>> import itertools
>>> result = list(itertools.chain.from_iterable(itertools.product(['-c'], k)))
This second form is certainly more compact, and probably more efficient ... but perhaps lacks some of the clarity and elegance one might expect from Python.
Is there another solution?
