Python
From FUKTwiki
Python is a programming language.
It is:
- Interpreted, which means it is not normally compiled into machine code.
- Garbage collecting, which means it allocates memory and creates and destroys objects automatically.
- Dynamically typed, which means that variables do not have a type, only values have a type.
- Widely used.
- Very actively developed and improved.
- Object-oriented, although it does not force this onto the programmer.
- Powerful, since it has many advanced data types and a very large standard library.
- Platform-independent.

[edit] Example Code
import locale locale.setlocale(locale.LC_ALL, "") print u"Hello world!"
[edit] Functions
def do_nothing(): pass def one(): return 1 def add_one(x): return x+1 def print_number(n): print "Number:", n
With the above functions defined, print_number(add_one(one()))
would print “Number: 2
”.
# A more complex function demonstrating more of the language. def blargh(x, y, z=None): """This function is just nonsense.""" if z is None: z = x + y else: z += x while z > x: y += z z -= 1 return y, z
Note that the language does not have any { braces } like C or Java, or any BEGIN/END constructs. Instead, the whitespace determines where a block of code ends.
[edit] Classes
# This class does nothing. class Empty(object): pass # This class inherits from “Empty” and has a method. class Foo(Empty): def bar(self): return "baz" # This class has a constructor which takes no arguments. The # constructor creates an attribute named "some_string". class Bar(object): def __init__(self): self.some_string = "whatever" def pretty_value(self): return "The value is: " + self.some_string
The language has many datatypes, like unicode strings, lists (like a C++ std::vector
), dictionaries (an associative array, like a C++ std::map
), sets and more. The language also has advanced features like exceptions, iterators, generators, introspection, metaclasses, etc.
