本文實例為大家分享了python實現(xiàn)按首字母分類查找的具體代碼，供大家參考，具體內(nèi)容如下

成都創(chuàng)新互聯(lián)公司長期為成百上千家客戶提供的網(wǎng)站建設(shè)服務(wù)，團隊從業(yè)經(jīng)驗10年，關(guān)注不同地域、不同群體，并針對不同對象提供差異化的產(chǎn)品和服務(wù)；打造開放共贏平臺，與合作伙伴共同營造健康的互聯(lián)網(wǎng)生態(tài)環(huán)境。為吐魯番企業(yè)提供專業(yè)的網(wǎng)站建設(shè)、做網(wǎng)站，吐魯番網(wǎng)站改版等技術(shù)服務(wù)。擁有10多年豐富建站經(jīng)驗和眾多成功案例,為您定制開發(fā)。

要求：

1.自己查找一些英文詞匯，存儲到某個容器類中
2.根據(jù)英文詞匯的首字母進行分類，類似于手機通訊簿中的快速查找功能
3.根據(jù)用戶輸入的字母，找到該字母開頭的所有單詞

#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("輸入一個字母，列出所有以此字母開頭的單詞:")
 if len(startLetter)!=1:
 print "必須是一個字母"
 else:
 reLexicons=[] #結(jié)果列表
 for x in xrange(len(lexicons)):
  lexicon=lexicons[x]
  if lexicon[0].lower()==startLetter.lower():#都轉(zhuǎn)為小寫后比較 開頭字母不區(qū)分大小寫
  reLexicons.append(lexicon)
 if len(reLexicons)==0:
  print "沒有結(jié)果"
 else:
  for x in xrange(len(reLexicons)):
  print reLexicons[x]
