Implement write, read, copy, batch rename files in Python

1. Writing content to a file

def write_file():    open_file = open("xxxx.txt","w")    open_file.write("i want to open a file and write this.\n")    open_file.close()write_file()

2. Read the contents of the file

#思路：1.以什么方式打开 2.读取文件 3.关闭文件def read_file():    read_file = open("xxxx.txt","r")    content = read_file.read()    print(content)    read_file.close()read_file()

3. Copying files

‘‘‘思路：    1.获取用户要复制的文件名    2.执行复制        2.1打开要复制的文件名        2.2新建一个文件        2.3从旧文件中读取数据，并且写入到新文件中    3.关闭文件‘‘‘def copy_file():    #1.获取用户要复制的文件名    old_file_name = input("请输入要复制的文件名：")    #2.1打开要复制的文件名    old_file = open(old_file_name,"r")    #2.2新建一个文件名    position = old_file_name.rfind(".")    new_file_name = old_file_name[:position] + "[复件]" + old_file_name[position:]    new_file = open(new_file_name,"w")    #2.3从旧文件中读取数据，并且写入到新文件中    while True:        content = old_file.read(1024)        if len(content) == 0:            break        new_file.write(content)    #关闭文件    old_file.close()    new_file.close()copy_file()

4. Batch Rename
1) Environment preparation

    mkdir /appdata/test/    cd /appdata/test/;touch {1..10}.txt;ll    [[email protected] test]# cd /appdata/test/;touch {1..10}.txt;lltotal 0-rw-r--r-- 1 root root 0 May  6 15:59 10.txt-rw-r--r-- 1 root root 0 May  6 15:59 1.txt-rw-r--r-- 1 root root 0 May  6 15:59 2.txt-rw-r--r-- 1 root root 0 May  6 15:59 3.txt-rw-r--r-- 1 root root 0 May  6 15:59 4.txt-rw-r--r-- 1 root root 0 May  6 15:59 5.txt-rw-r--r-- 1 root root 0 May  6 15:59 6.txt-rw-r--r-- 1 root root 0 May  6 15:59 7.txt-rw-r--r-- 1 root root 0 May  6 15:59 8.txt-rw-r--r-- 1 root root 0 May  6 15:59 9.txt

2) Program section

‘‘‘思路：    1.获取要重命名的文件的文件夹路径    2.获取所有要重命名的文件    3.执行重命名‘‘‘import osdef rename_batch():    #1.获取文件夹    folder_name = input("请输入要重命名文件的文件夹路径：")    #2.获取所有文件名    file_names = os.listdir(folder_name)    #3.重命名    for name in file_names:        print(name)        old_file_name = folder_name + "/" + name        new_file_name = folder_name + "/" + "huwho出品-" + name        os.rename(old_file_name,new_file_name)         print(new_file_name)rename_batch()

3) Execution Results section

python rename_batch.py 请输入要重命名文件的文件夹路径：/appdata/test1.txt/appdata/test/huwho出品-1.txt2.txt/appdata/test/huwho出品-2.txt3.txt/appdata/test/huwho出品-3.txt4.txt/appdata/test/huwho出品-4.txt5.txt/appdata/test/huwho出品-5.txt6.txt/appdata/test/huwho出品-6.txt7.txt/appdata/test/huwho出品-7.txt8.txt/appdata/test/huwho出品-8.txt9.txt/appdata/test/huwho出品-9.txt10.txt/appdata/test/huwho出品-10.txt
