String sequence in Jython wsadmin

 String sequence in Jython

Strings are set of characters enclosed with single quotes or double or triple quotes. String objects are similar to tuple sequence objects. String objects are immutable. You cannot change the current string content. We need to use the new string object for modify the contents.

Strings can be two variants:

1. raw string
2. normal string

All the help method out comes are raw strings they are parsed when it is given to print command.

wsadmin>rawstr=AdminTask.help()
wsadmin>rawstr
'WASX8001I: The AdminTask object enables the execution of available admin\n\tcommands.  AdminTask commands operate in two modes:\n\tthe default mode is one which AdminTask communicates with the WebSphere\n\tserver to accomplish its task. A local mode is also available, in which\n\tno server communication takes place. The local mode of operation is\n\tinvoked by bringing up the scripting client using the command line\n\t"-.

wsadmin>print rawstr

You can say WASShell that don't parse the string, keep as it as raw string. To define raw string r'' must be prefixed for the string.

wsadmin>scriptpath='c:\scripts\test'
wsadmin>scriptpath
'c:\\scripts\test'
wsadmin>print scriptpath
c:\scripts      est
wsadmin>scriptpath=r'c:\scripts\test'
wsadmin>print scriptpath
c:\scripts\test

 Jython String functions

There are nearly 40+ string functions available in Python. Almost same works in Jython as well.
Lets experiment on simple string

wsadmin>serverid=AdminConfig.getid('/Server:server1')
wsadmin>serverid
'server1(cells/ubuntu-was8Node01Cell/nodes/ubuntu-was8Node01/servers/server1|server.xml#Server_1183121908656)'
wsadmin>s=serverid

The split() function

Strings can be split with a delimiter which can be any symbol or a character.
Let us split the string with '#' symbol. And also test the endswith() function in the for loop.

wsadmin>s.split('#')
['server1(cells/ubuntu-was8Node01Cell/nodes/ubuntu-was8Node01/servers/server1|server.xml', 'Server_1183121908656)']

wsadmin>for e in s.split('/'):
wsadmin> if e.endswith('Cell'): print e
wsadmin>
ubuntu-was8Node01Cell

String operations

Repetition with * operator

wsadmin>d='=*'
wsadmin>print d * 50
=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*

Concatenation of string

wsadmin>s1="WebSphere Adminitration"
wsadmin>s2='wsadmin automation'
wsadmin>s3=s1+s2
wsadmin>print s3
WebSphere Adminitrationwsadmin automation

The strip functions, startswith, endswith, lower, upper, find functions

As you know strings are immutable you can translate when printing to stdout or screen.

s="Kishore,Wsadmin"
print s.split(",")

s1="    string strip example    "
print "s1.rstrip :", s1.rstrip()
print "lstrip :", s1.lstrip()
print "strip :", s1.strip()

print "endswith :", s.endswith('n')
print "endswith :", s.endswith('in')
print "startswith :", s.startswith('k')

print "lower case :", s.lower()
print "upper case  :", s.upper()

print "find substring :", s.find('shore')
print "replace substring  :", s.replace('Wsadmin','websphereadmin')

output

wsadmin>execfile('/home/vagrant/scripts/strfun.py')
['Kishore', 'Wsadmin']
s1.rstrip :     string strip example
lstrip : string strip example
strip : string strip example
endswith : 1
endswith : 1
startswith : 0
lower case : kishore,wsadmin
upper case  : KISHORE,WSADMIN
find substring : 2
replace substring  : Kishore,websphereadmin

General string function
x="k"
if x in s1:
        print "it is present"
else:
        print "it is not present"
x="K"
if x not in s1:
        print "it is not present"
else:
        print "it is present"
print "slicing",s1[2:6]

print "slicing",s1[2:]

print "slicing",s1[0:3],s1[:3]
