Python中for j in range(0, len(files)): NameError: name 'files' is not defined

Question

代码：

for root, dirs, files in os.walk('groupmailroger'):
    print(files) #当前路径下所有非目录子文件
    print(root)
    count = 0
    for i in range(0, len(receiversAddressName)):
        for j in range(0, len(files)):
            if (bool(re.search(str(receiversAddressName[i]), str(files[j]))) == True):
                count = count + 1
    SendFlag = False
    if count != len(receiversAddressName):
    print("错误！！！ 收件人名称和附件名称不一致！！！")
    else:
SendFlag = True

报错：

  File "SendMail.py", line 11
    print("错误！！！ 收件人名称和附件名称不一致！！！")
    ^
IndentationError: expected an indented block

Process finished with exit code 1

请问改如何解决呢？

代码格式移位导致程序错误,按下面修改即可

for root, dirs, files in os.walk('groupmailroger'):
    print(files) #当前路径下所有非目录子文件
    print(root)
    count = 0
    for i in range(0, len(receiversAddressName)):
        for j in range(0, len(files)):
            if (bool(re.search(str(receiversAddressName[i]), str(files[j]))) == True):
                count = count + 1
