python实现每次处理一个字符的三种方法

a_string = "abccdea"  print 'the first' for c in a_string:   print ord(c)+1     print "the second"   result = [ord(c)+1 for c in a_string] print result  print "the thrid"  def do_something(c):   return ord(c)+1  result = map(do_something ,a_string) print result 

the first 98 99 100 100 101 102 98 the second [98, 99, 100, 100, 101, 102, 98] the thrid [98, 99, 100, 100, 101, 102, 98]
