从零开始的python之旅（day4）

从零开始的python之旅（day4）

  昨天博客园好像崩了，所以昨天晚上没写，就挪到今天来补了，昨天主要是文件操作，话不多说，上代码

  addressBook

def main():
    file1 = open('TeleAddressBook.txt','rb')
    file2 = open('EmailAddressBook.txt','rb')
    file1.readline()
    file2.readline()
    list1 = file1.readlines()
    list2 = file2.readlines()
    # print(list1)
    list1_name = []
    list1_tele = []
    list2_name = []
    list2_email = []
    for i in list1:
        el = i.split()
        list1_name.append(str(el[0].decode('gbk')))
        list1_tele.append(str(el[1].decode('gbk')))
    for i in list2:
        el = i.split()
        list2_name.append(str(el[0].decode('gbk')))
        list2_email.append(str(el[1].decode('gbk')))
    list3 = []
    list3.append('姓名\t    电话   \t  邮箱\n')
    for i in range(len(list1_name)):
        s = ''
        if list1_name[i] in list2_name:
            j = list2_name.index(list1_name[i])
            s = '\t'.join([list1_name[i],list1_tele[i],list2_email[j]])
        else :

        s += '\n'

            s += '\n'
            list3.append(s)

    file3 = open('addressbook.txt','w')
    file3.writelines(list3)
    file1.close()
    file2.close()
    file3.close()

    main()

  这段程序主要是将两个文件合并，在此处没啥问题，可以看看day5差不多类似代码，换种方法读入

  在这段程序中，读取文章内容（英文）然后转化大小写等等一系列操作后，统计单词出现频率然后利用turtle画出来。

  day4主要是，文件处理和turtle库的进阶。文件处理时，还是要注意，encoding和decode的类型类型选择。其他的没啥了
