Python批量创建和修改文件名案例

import os
import glob
from shutil import copyfile
import pandas as pd

path = input(r"请输入文件夹地址：")
os.chdir(path)

请输入文件夹地址：C:\Users\Administrator\Desktop\files

os.chdir(path)
total_num = int(input(r'请输入班级人数:'))
path_file_number = glob.glob("*.jpg")  #获取当前文件夹下个数
num = len(path_file_number)
source_file = [i for i in os.listdir(path)][0]
[
    copyfile(source_file, f"{i}" + ".jpg") for i in range(0, total_num - num)
    if num <= total_num
]
print("创建成功")

创建成功

    r"青年大学习\18541花名册.xlsx")

    print("修改成功")
