2.根据英文词汇的首字母进行分类，类似于手机通讯簿中的快速查找功能
3.根据用户输入的字母，找到该字母开头的所有单词

#coding=utf-8
lexicons=["the","be","of","and","A","to","in","he","have","it","that","for","they","I","with","as","not","on","she","at","by","this","we","you","do","but","from","or","which","one","would","all","will","there","say","who","make","when","can"]
while True:
 startLetter=raw_input("输入一个字母，列出所有以此字母开头的单词:")
 if len(startLetter)!=1:
 print "必须是一个字母"
 else:
 reLexicons=[] #结果列表
 for x in xrange(len(lexicons)):
  lexicon=lexicons[x]
  if lexicon[0].lower()==startLetter.lower():#都转为小写后比较 开头字母不区分大小写
  reLexicons.append(lexicon)
 if len(reLexicons)==0:
  print "没有结果"
 else:
  for x in xrange(len(reLexicons)):
  print reLexicons[x]
