Points to Remember in jython

Points to Remember

The basic rules to write a Jython program are:

Code execution

Statements are executed in sequence up to a control structure: if, for, while, raise , or a function call.

Block

A block is defined by lines with the same indentation level (spaces or tabulations).

Statements

A statement stops at the end of a line, and can be continued on several lines if they end with a \, or if they are enclosed in (), [], {} or '''.  Several instructions can be on the same line if they are separated with a ;.

Comments

A comment starts with a hash character # and ends at the end of the physical line.

String Documentation

If a function, a module or a class starts with a string constant, this string is stored in the __doc__ attribute of the object.

Examples

Simple program that displays "Hello World"
# Assign a value to a string
s = 'Hello World'
# Display the value
print s

Program that displays "Hello World" 4 times
s = 'Hello World %d'
for i in range(4):
   j = i * 2
   print s % j
