Python—将一个文件复制到另一个文件以及合并两个文件

题目：

1.编程实现将文件 file1 的内容复制到文件 file2 中。
2.有一个职工通讯信息文件"TeleAddressBook. txt”，内容为

解答：

1、编程实现将文件file1的内容复制到文件file2中。

思路：首先新建文件夹file1，其中新建了AddressBook.txt、EmailAddressBook.txt、TeleAddressBook.txt三个文本文件，其次在spyder（python3.8）中编写代码，最后通过运行代码将文件file1的内容复制到文件file2中。

代码如下：

#-*-coding: utf-8 -*-
import shutil
shutil.copytree(r'E\pywork\py\file1',r'E\pywork\py\file2')

运行结果：


导入shutil 库
Shutil.copytree(来源路径，目标路径) 函数表示复制整个文件路径

2.有一个职工通讯文件”TeleAddressBook.txt”,另外有一个职工邮箱信息文件“Email AddressBook.txt”，将这两个文件合并为职工信息文件“Address Book.txt”。

**思路：**首先在文件file1中创建TeleAddressBook.txt、AddressBook.txt两个文本文件，再分别输入其对于的内容，其次在spyder（python3.8）中编写代码，最后得到如下所示的运行结果图。

代码如下：
较规范表达

# -*-coding:utf-8*-

def main():

    file1 = open("C:\python.exp2\TeleAddressBook.txt", "r")

    file2 = open("C:\python.exp2\EmailAddressBook.txt", "r")

    file1.readline()

    file2.readline()

    lines1 = file1.readlines()

    lines2 = file2.readlines()
    
    # 建立空列表用于存储姓名电话Email

    list1_name = []

    list1_tele = []

    list2_name = []

    list2_email = []

    # 获取TeleAddressBook

    for line in lines1:

        elements=line.split()

        list1_name.append(str(elements[0]))

        list1_tele.append(str(elements[1]))



    # 获取EmailAddressBook

    for line in lines2:

        elements=line.split()

        list2_name.append(str(elements[0]))

        list2_email.append(str(elements[1]))



    lines = []



    lines.append("Name\tTele\t\tEmail\n")

    #按索引方式遍历姓名列表

    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]])

            s += "\n"

        else:

            s = "\t".join([list1_name[i],list1_tele[i], str("-----------")])

            s += "\n"

        lines.append(s)

    for i in range(len(list2_name)):

        s = ""

        if list2_name[i] not in list1_name:

            s = "\t".join([list2_name[i], str("-----------"), list2_email[i]])

            s += "\n"

        lines.append(s)



    # 将新生成的合并数据写入新的文件中

    file3 = open("C:\python.exp2\AddressBook.txt", "w", encoding='UTF-8')

    file3.writelines(lines)



    # 关闭文件

    file3.close()

    file1.close()

    file2.close()

    print("The addressBooks are merged!")



if __name__ == "__main__":

    main()
