python 遍历

##one
for letter in 'Python':
 print 'Current Letter : ',letter


##two
fruits = ['banana','apple','mange']
for i  in range(len(fruits)):
   print i ,fruits[i]

 

l = [1,2,3,'a','c']
s = (1,2,3,'b','c')
d = {1:'a',2:'b',3:'c'} ##字典
for x in l:
   print x

for a in range(len(s)):
   print s[a]

for dic in d :
 print dic   
 print d[dic] ##用for 遍历字典时只能得出key值。

for k,v in d.items(): ##用items 就可以把字典中的key值和value值给遍历出来。
    print k
    print v
