-// This is the original article from [[anonymous:insurgency-wiki|Insurgency Wiki]] for [[tools:python|Python]], when **Python 2** was still current. The following applies to **Python 2.6 and lower**: // +
- +
-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 +
-  3.528 +
-  >>> print b/25 +
-  3 +
-  >>> #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... +
