Concatenation of items in list

Question

I have such a list:

['S/M - Black', ' 93094-01']

It is the result of:

m['value'].split(',')[0:2:]

How can I produce such a string from it:

'S/M - Black, 93094-01'

I have tried:

print [i + ', ' + i for i in m['value'].split(', ')[0:2:]]

But it gives me:

['S/M - Black, S/M - Black', ' 93094-01,  93094-01']

as a side note, just `[:2]` would be fine. – georg Jun 26 '14 at 10:20 — georg, Jun 26 '14 at 10:20

As you have seen,

[i + ', ' + i for i in m['value'].split(', ')[0:2:]]

applies that format to each item in turn. Instead, you want:

", ".join(m['value'].split(",")[:2])

(note the neater slice, which means "the first two items"). For example:

>>> ", ".join(['S/M - Black', ' 93094-01'])
'S/M - Black,  93094-01'

You should use the join method:

",".join(m['value'].split(', ')[0:2:])

The .split function returns a list, read docs here https://docs.python.org/2/library/stdtypes.html

So you can join you're list values by using ','.join(['S/M - Black', ' 93094-01']) as answered earlier on a similar question Concatenate item in list to strings
