Python is a very high-level dynamic object-oriented programming language that can be used for many kinds of software development. It has been used to creating a few bot systems on dAmn.

Basic syntax
Strings
string = "This is a string in Python!"
Different types of quote marks work with Python:
# This will work. string = "Python string's rock!" # This will too. string = 'Python strings rock!' # Escaping quote marks normally string = 'Python string\'s rock!'
To print a string, issue the print statement:
print "Hello, world!"
You can also simply save it in variables and then handle variables like in most other languages.
string = "This is a Python string!" print string
Writing multi-line strings in Python is done using triple quotes: """ or ''', like so:
print """ This is an example of a multi-line string in python. """
Strings can also be concatenated, and the easiest method of achieving this is using the + operator:
string = 'this is' + ' ' + 'a string'
Strings can also be repeated with the * operator:
print "test" * 5 # outputs: testtesttesttesttest
Strings also support indexes:
string = 'test0' print string[4] # outputs: t
We printed the 4th indexed character in the string, which is "t" in this case.
Lists
Lists (known as non-associative arrays in other languages) are fairly easy, below is a simple example of how to use them:
l = ['bot', 'dom'] print l # outputs: ['bot', 'dom'] print l[0] # outputs: bot print l[1] # outputs: dom
You can also merge several lists using the + operator
print ['bot','dom'] + ['foo','bar'] # outputs: ['bot','dom','foo','bar']
