Python built-in functions (iii)

The python built-in functions now need to know as follows:

Code:

  #!/usr/bin/env python   
  #-*-coding:utf-8-*-
   
  # author by LH   
 
 #map (functions, objects that can be iterated) 
 Def F1 (x): 
 return x+100 
 Ret=map (f1,[1,2,3,4,5]) 
 for i in RET: 
 Print i 
 PR int '---------------------------------------' 
 #hash转换成哈希值, save memory 
 dic={
 ' dvfhsuicbfhascjnbj ': ' 123 ' 
} 
 R=hash (' dvfhsuicbfhascjnbj ') 
 Print R 
 print '---------------------------------------' 
 # Isinstance determines whether an object is created by a class 
 Li=[11,22,33] 
 r=isinstance (li,list) 
 Print R 
 print '----------------------- ----------------' 
 
 #iter创建一个可迭代的对象 
 Obj=iter ([11,22,33,44]) 
 R1=next (obj) 
 print R1 
 print '------ ---------------------------------' 
 #zip 
 li1=[11,22,33,44] 
 li2=[' A ', ' B ', ' C ', ' d '] 
 R=zip (li1,li2) 
 For I in R: 
 Print I 

Operation Result:
