Check if a tuple contains a string

[ennoil]

I have a tuple of a tuple (ServerList) that contains the following:

<host1>,DEV,Inf ormatica,Red_Ha t,64
<host2>,PROD,In formatica,Red_H at,64
<host3>,PROD,In formatica,Red_H at,64
<host4>,QA,Info rmatica,Red_Hat ,64
<host5>,PROD,Ti bco,Solaris,
<host6>,TEST,Ti bco,Solaris,

I have a list (EnvList) that could contain the following:

['PROD','Informa tica','Red_Hat' ,'64']

or any combination.

Using the the example above I want to create a list which contains:

['<host2>','<hos t3>']

I am hoping for something like

for i in ServerList:
  if i contains EnvList:
    ServerName.append(ServerList[0])

How can this be actually done?

You can do it like this:

serverList = (("<host1>","DEV","Informatica","Red_Hat","64"),
              ("<host2>","PROD","Informatica","Red_Hat","64"),
              ("<host3>","PROD","Informatica","Red_Hat","64"),
              ("<host4>","QA","Informatica","Red_Hat","64"),
              ("<host5>","PROD","Tibco","Solaris"),
              ("<host6>","TEST","Tibco","Solaris"))

envList = [['PROD','Informatica','Red_Hat','64'], ["PROD","Tibco","Solaris"]]

output = []
for item in serverList:
    if list(item[1:]) in envList:
        output.append(item[0])

Note that the objects being compared must evaluate to be equal in order to work.

Part of the problem is that not all of the 4 items in EnvList need to exist.
For example, if I want to pick just the Solaris servers out of the ServerList then EnvList will only contain
['Solaris']
EnvList is created through a series of menus from which the user will pick only then EnvList items that they need.

You will need an additional loop.

serverList = (("<host1>","DEV","Informatica","Red_Hat","64"),
              ("<host2>","PROD","Informatica","Red_Hat","64"),
              ("<host3>","PROD","Informatica","Red_Hat","64"),
              ("<host4>","QA","Informatica","Red_Hat","64"),
              ("<host5>","PROD","Tibco","Solaris"),
              ("<host6>","TEST","Tibco","Solaris"))
envList = [['PROD','Red_Hat','64'], ["PROD","Solaris"]]

output = []
for item in serverList:
    for elem in envList:
        if set(elem).issubset(set(item[1:])):
            output.append(item[0])
            
print output

The results:

>>> ['<host2>', '<host3>', '<host5>']
>>>
