 ====== Python ======
-Below applies to Python 2.6 or lower, Python 3 is a good bit different.
+//stub page for **Python 3**. the original article that had this namespace has been moved to [[tools:python2|Python 2]].//
-Python is an object oriented, interpreted language. It is unique in that it requires a user to indent in place of using curly brackets ({..}).
-Note: that most *nix distributions come with Python by default.
-===== Basics =====
-//Basic// python syntax
-==== Hello World! ====
-  >>> print "HELLO WORLD!"
-  HELLO WORLD!
-==== Variables ====
-Variable names DO NOT need to begin with a special character, unlike PHP. Variable names CAN, however, be any combination, as long as the word isn't reserved (Ex: and, or, print), of letters and numbers.
-  >>> #Numbers
-  >>> a = 1 #Declare A as 1
-  >>> b = a+5 #b becomes 6, while a remains 1
-  >>> a += 5 #a is overwritten, and becomes 6
-  >>> c = b = a #c and b are overwritten and become 6
-  >>> #Strings
-  >>> a = "Hello "
-  >>> b = "There"
-  >>> c = a+b #JOIN STRINGS
-  >>> a = "Blue Yellow Green Red".split(" ") #Split the string at every " "
-  >>> a #Output 'a' to the screen, same as print or print()
-  ['Blue', 'Yellow', 'Green', 'Red'] #List object, another type of variable
-  >>> .join(a) #Join all the list objects as one
-  'BlueYellowGreenRed'
-  >>> a = 'Blue Green Yellow Red'[0:4] #This returns the sub-string 'Blue'
-  >>> a = 'Blue Green Yellow Red'[5:] #This returns the sub-string 'Green Yellow Red'
-  >>> a = 'a = 'Blue Green Yellow Red'[::2] #This returns the sub-string Bu re elwRd'
-  >>> #Float
-  >>> a = 88.2
-  >>> b = 88
-  >>> print a/25
-.528
-  >>> print b/25
-  >>> #Other types
-  >>> a = (" ", 355, 256.7, ["Hello", "World"])
-  >>> type(a)
-  <type 'tuple'>
-  >>> a = {"Hello":"World", "Key":"Value"}
-  >>> type(a)
-  <type 'dict'>
-  >>> a = "Anhero"
-  >>> del a #Its a good idea, if you're making a 'hidden' script, to delete variables after you use them...
-===== Statements =====
-==== Comparison ====
-  <       Less than
-  >       Greater than
-  ==      Equal to
-  !=      Not equal
-  is      Identical
-  is not  Not identical
-  <=      Less than or equal to
-  >=      Greater than or equal to
-=== If ===
-  >>> a = 1
-  >>> b = 2
-  >>> if a != b:
-  	print "No!"
-  No!
-  >>> a = 1
-  >>> b = 1
-  >>> if a == b:
-  	print "Yes!"
-  Yes!
-  >>> a = 1
-  >>> b = 5
-  >>> if (a == b-len("....")/1) and "a" == "a" or "b" == "b":
-  	print "Yes!"
-  Yes!
-==== Loops ====
-=== While ===
-  >>> a = 1
-  >>> while a < 5: #Note, replacing '<' with '<=' allows it to reach 5, instead of stopping at 4
-	print a
-	a += 1;
-  >>> a = False;
-  >>> while a == False:
-	print "False"
-	a = True;
-  False
-=== For ===
-  >>> for x in range(0, 10):
-  	print x
-//consider using xrange when dealing with larger lists, as it creates an iterator, rather than constructing the full list in memory//
-  >>> for x in ['Hello', 'world', ',this', 'is', 'a', 'list']:
-	print x
-  Hello
-  world
-  ,this
-  is
-  a
-  list
