Often there is a need to run a task across a set of machines. The list of IP addresses for these machines could come from different sources and therefore be in different formats. Starting with a file that contains mainly IP addresses, one per line, your task is to write a function that converts the list of IP addresses into a comma separated list of IP address, ignoring any line that starts with a # and ignoring any line that does not contain a valid IP address. Input: A sample inventory file which may contain various text and comments along with valid and invalid IP addresses. For example: [zone1] 10.171.102.174 #10.171.102.195 10.171.102.182 [zone2] 10.171.3.172 10.171.3.21 #10.171.3.224 Output: The list of IP addresses separated by commas. For the above example, that would be: 10.171.102.174,10.171.102.182,10.171.3.172,10.171.3.21
