    这篇文章主要为大家详细介绍了Python编写电话薄实现增删改查功能的相关资料,感兴趣的朋友可以参考一下
    初学python,写一个小程序练习一下。主要功能就是增删改查的一些功能。主要用到的技术:字典的使用,pickle的使用,io文件操作。代码如下:

    import pickle #studentinfo = {'netboy': '15011038018',\ # 'godboy': '15011235698'} studentinfo = {} FUNC_NUM = 5 def write_file(value): file = open('student_info.txt', 'wb') file.truncate() pickle.dump(value, file, True) file.close def read_file(): global studentinfo file = open('student_info.txt', 'rb') studentinfo = pickle.load(file) file.close() def search_student(): global studentinfo name = input('please input student\'s name:') if name in studentinfo: print('name:%s phone:%s' % (name, studentinfo[name])) else: print('has no this body') def delete_student(): global studentinfo name = input('please input student\'s name:') if name in studentinfo: studentinfo.pop(name) write_file(studentinfo) else: print('has no this body') def add_student(): global studentinfo name = input('please input student\'s name:') phOne= input('please input phone:') studentinfo[name] = phone write_file(studentinfo) def modifiy_student(): global studentinfo name = input('please input student\'s name:') if name in studentinfo: phOne= input('please input student\'s phone:') studentinfo[name] = phone else: print('has no this name') def show_all(): global studentinfo for key, value in studentinfo.items(): print('name:' + key + 'phone:' + value) func = {1 : search_student, \ 2 : delete_student, \ 3 : add_student, \ 4 : modifiy_student, \ 5 : show_all} def menu(): print('-----------------------------------------------'); print('1 search student:') print('2 delete student:') print('3 add student:') print('4 modifiy student:') print('5 show all student') print('6 exit') print('-----------------------------------------------'); def init_data(): global studentinfo file = open('student_info.txt', 'rb') studentinfo = pickle.load(file) #print(studentinfo) file.close() init_data() while True: menu() index = int(input()) if index == FUNC_NUM + 1: exit() elif index  FUNC_NUM + 1: print('num is between 1-%d' % (FUNC_NUM + 1)) continue #print(index) func[index]()
    以上就是本文的全部内容,希望对大家学习Python程序设计有所帮助。
