Jython Basics

Posted on by

Below are the code sample which shows how to carry out basic tasks in Jython.The Files should be shared as .py extension if your are using eclipse.To know abount configuring jython in eclipse follow the

Printing a Message in Console

  print 1 + 1
  print "Hello" + " World "
  print "Hello Jython "
  print "Jython ", "Scripting"

Simple Jython Function that Takes Argument and Print Values

def displayName(x):
 print x 
 
displayName("Mugil")

Jython Function which Calculates the Factorial of a Number

def factorial(x):
 if x<=1 : 
  return 1    
 return x * factorial(x-1)
 
print factorial(3)

Function which compares Two Strings in If Condition

def compareName(FirstName, LastName):
 if FirstName == LastName:
  print "They are Equal"
 else:
  print "They are Not Equal"  
   
   
compareName("Jython", "Jython")

Conditional Operators
Function which Perform AND, OR and Not Ops

def BoolOps(pOne, pTwo): 
 if pOne and pTwo:
  print "They are Equal"
 else:
  print "They are Not Equal" 
  
BoolOps(1,0)

Jython Conditional Operators

Jython Supports Three Numeric Values as Below

  • Integers
  • Long
  • Floating Point

Array from Delimited String and Looping through It

Names = "A, B, C, D, E"

arrNames = Names.split(",")

for x in range(len(arrNames)):
 print arrNames[x]

Array Function

Names = "A,B,C,D,E,F,G,H,I,J,K,L,M"

arrNames = Names.split(",")

#B
print arrNames[1]

#['B']
print arrNames[1:2]

#['B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M']
print arrNames[1:]

#['A', 'B', 'C', 'D', 'E', 'F']
print arrNames[:6]

#['B', 'C', 'D', 'E']
print arrNames[1:5]

#['H', 'I', 'J']
print arrNames[-6:-3]

#['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M']
print arrNames[:]

#['A', 'C', 'E', 'G', 'I', 'K', 'M']
print arrNames[::2]

Concatenating Two Arrays together

Names1 = "A,B,C"
Names2 = "D, E, F"

arrNames1 = Names1.split(",")
arrNames2 = Names2.split(",")

arrNames = arrNames1 + arrNames2

for i in range(len(arrNames)):
 print arrNames[i]
