Hi,
could you actually help me further?
I thought it will quite easy but I've been programming in python just
for a month.
I need to add extra items in new list.
So here is example:
I have a list of dictionaries.
e.g.
[{'index': 0, 'ip_addr': '1.2.3.4', 'server-name':'Asterisk', 'transport':
'udp', 'service_domain': 'dp0.example.com'},
{'index': 1, 'ip_addr': '5.6.7.8', 'server-name':'Asterisk', 'transport':
'udp', 'service_domain': 'dp1.example.com'},
{'index': 0, 'ip_addr': '1.2.3.4', 'server-name': 'Yes', 'transport': 'tcp',
'service_domain': 'dp0.example.com'},
{'index': 1, 'ip_addr': '5.6.7.8', 'server-name': 'Yes', 'transport': 'tcp',
'service_domain': 'dp1.example.com'}]
The server-name within tcp test is not known because I just open connection at
port where the server should run and if succeeded then server-name = Yes. In
newlist should be the server name Asterisk though.
how could I make a new list of dictionaries which would look like:
[{'transports': ['udp','tcp'], 'service_domain': 'dp0.example.com', 'ip_addr':
'1.2.3.4', 'server-name':'Asterisk'},
{'transports': ['udp','tcp'], 'service_domain': 'dp1.example.com', 'ip_addr':
'5.6.7.8', 'server-name':'Asterisk'}]
I was trying to implement it to existing code but I'm not really
successful so far.
Thank you for your help.
