Jython operators and sequences in wsadmin

Welcome back to Jython learning blog again. today I have explored different categories of operators how they can be used in Jython for wsadmin. prerequisites for this is you must have a Jython for WebSphere installed on your VM and you are on wsadmin prompt.

Types of operators (inherited from Python):

• Arithmetic operators
• Comparison operators
• Relational operators 

These simple experiments would give you a base for building automation scripts in your projects.

Jython Operators on wsadmin

 

How can Jython deals with Arithmetic operators

Every language supports the Arthematic operators and in Jython same operators as in C or Python languages.

wsadmin>x,y = 10, 20
wsadmin>print x, y
10 20
wsadmin>x+y
30
wsadmin>x+y+30
60
wsadmin>y-x
10
wsadmin>x-y
-10
wsadmin>x*y
200
wsadmin>x**2
100
wsadmin>y/x
2
wsadmin>y%x
0

How to use Jython Comparison operators?

The comparing operators mostly used in the 'if-else' or 'while' blocks which returns either True or False value. For each data type it will be different so see the examples executed at the wsadmin prompt.

Numeric comparison in Jython

 wsadmin>10>1

Tuple comparison in Jython

wsadmin>'app_server1' in ('app_server1','app_server2','ejb_server1','ejb_server2')
1
wsadmin>servers_list=('app_server1','app_server2','ejb_server1','ejb_server2')
wsadmin>'appserver1' in servers_list
0

wsadmin>['dev_cell01',20]==[20,'dev_cell01']
0

Dictionaries comparison in Jython

wsadmin>{'appserver1':8001}=={'appserver1':8001}
1
wsadmin>server_dict={'appserver1':8001}
wsadmin>{'appserver1':8001}==server_dict
1
wsadmin>server_dict=={'appserver2':8001}
0

How can Jython Relational operators simplify your scripts?

Here is the set of releational operators usage examples

wsadmin>x>=10
1
wsadmin>x>=10 and y==20
1
wsadmin>x>10 or y==20
1
wsadmin>x>10
0
wsadmin>not x>10
1
wsadmin>not x>=10
0
