在Python中使用os.remove()发生异常

Question

请大家帮我解答下，调用os.remove()时发生异常

import os


def coffee_record_modify():

    flag = False

    file_coffee = open(r'C:\Users\yyf24\Desktop\coffee.txt', 'r')
    file_temp = open(r'C:\Users\yyf24\Desktop\temp.txt', 'w')

    search = input("请输入您要修改的咖啡种类：")

    description = file_coffee.readline().rstrip()

    while description != '':

        quantity = file_coffee.readline().rstrip()

        if description == search:
            modify_quantity = input("当前给种类咖啡的存量（磅）：")
            file_temp.write(description + '\n')
            file_temp.write(modify_quantity + '\n')
            flag = True
        else:
            file_temp.write(description + '\n')
            file_temp.write(quantity + '\n')

        description = file_coffee.readline().rstrip()

    file_coffee.close()
    file_temp.close()


    os.remove(r'C:\Users\yyf24\Desktop\coffee.txt')
    os.rename(r'C:\Users\yyf24\Desktop\temp.txt', r'C:\Users\yyf24\Desktop\coffee.txt')


    if flag:
        print("修改完成！")
    else:
        print("您所要修改的咖啡种类不存在！")


coffee_record_modify()

发生异常如下：
File "E:/yyf/Python_Basic/file/coffee_record_modify_v1.py", line 43, in coffee_record_modify
os.remove(r'C:\Users\yyf24\Desktop\coffee.txt')
PermissionError: [WinError 32] 另一个程序正在使用此文件，进程无法访问。: 'C:\Users\yyf24\Desktop\coffee.txt'
