Python replace string
Hi,

I have a python variable with a value like this :

Code:
string = "abc.de.fghijk.com:zyz.ab.fgfijk.com:abc.ef.fghijk.com"

They are hostnames separated by the special character ":" . From this string I want to make a list with values :

Code:
['abc','zyz','abc']

Code:
>>> uris
'abc.de.fghijk.com:zyz.ab.fgfijk.com:abc.ef.fghijk.com'
>>> domains = uris.split(':')
>>> hostnames = [ x.split('.')[0] for x in domains ]
>>> hostnames
['abc', 'zyz', 'abc']
>>>

Of course, you can do the whole thing in one line:
Code:
hostnames = [ x.split('.')[0] for x in uris.split(':') ]
