How can i split a string into two on the first occurrence of a character

Question

I have written a code to list all the components in my Linux server. The list is stored in a file. I will ready line by line and have to split the components from version and store in 2 different strings.

For eg: one of my line shows console-3.45.1-0 where console is the component and 3.45.1-0 is the version. If I use split,

print components[i].split('-')

I can see ['console', '3.45.1', '0\r\r'] which is not what I wanted. How can I split into 2 strings on the first occurrence of '-' ?

str.split takes a maxsplit argument, pass 1 to only split on the first -:

print components[i].rstrip().split('-',1)

To store the output in two variables:

In [7]: s = "console-3.45.1-0"

In [8]: a,b = s.split("-",1)

In [9]: a
Out[9]: 'console'

In [10]: b
Out[10]: '3.45.1-0'

@Roshanr, if you want to keep the `'\r\r'` remove the rstrip call – Padraic Cunningham Jul 20 '15 at 14:01
@Roshanr, added how to store the output – Padraic Cunningham Jul 20 '15 at 14:02
