#簡單的差看幫助文檔input(...)和raw_input(...)有如下區(qū)別 
>>> help(input) 
Help on built-in function input in module __builtin__: 
input(...) 
  input([prompt]) -> value 
  Equivalent to eval(raw_input(prompt)). 
>>> help(raw_input) 
Help on built-in function raw_input in module __builtin__: 
raw_input(...) 
  raw_input([prompt]) -> string 
    
  Read a string from standard input. The trailing newline is stripped. 
  If the user hits EOF (Unix: Ctl-D, Windows: Ctl-Z+Return), raise EOFError. 
  On Unix, GNU readline is used if enabled. The prompt string, if given, 
  is printed without a trailing newline before reading. 
  
#可見 input會根據(jù)輸入的內(nèi)容eval結(jié)果來返回值，即輸入純數(shù)字，則得到的就是純數(shù)字

#test：

>>> help(enumerate) 
Help on class enumerate in module __builtin__: 
 
class enumerate(object) 
 | enumerate(iterable[, start]) -> iterator for index, value of iterable 
 |  
 | Return an enumerate object. iterable must be another object that supports 
 | iteration. The enumerate object yields pairs containing a count (from 
 | start, which defaults to zero) and a value yielded by the iterable argument. 
 | enumerate is useful for obtaining an indexed list: 
 |   (0, seq[0]), (1, seq[1]), (2, seq[2]), ... 
 |  
 | Methods defined here: 
 |  
 | __getattribute__(...) 
 |   x.__getattribute__('name') <==> x.name 
 |  
 | __iter__(...) 
 |   x.__iter__() <==> iter(x) 
 |  
 | next(...) 
 |   x.next() -> the next value, or raise StopIteration 
 |  
 | ----------------------------------------------------------------------
 | Data and other attributes defined here: 
 |  
 | __new__ = <built-in method __new__ of type object> 
 |   T.__new__(S, ...) -> a new object with type S, a subtype of T
