Question

在使用for循环遍历目录时，在.xlsx文件上使用read_excel时遇到问题。执行以下操作时：

df1 = pd.read_excel('***.xlsx')
df2 = pd.read_excel('***.xlsx')

df = pd.concat([df1,df2], ignore_index=True, sort=False)

我没有问题。但是当我尝试在循环中读取相同的文件时：

directories_to_check = [
        "C:\\Users\\***"
        ]
files = []
for directory in directories_to_check:
    directories = [d for d in listdir(directory) if isdir(join(directory,d))]
    print(directories)
    for root in directories:
        path = join(directory,root)
        print(path)
        for file in listdir(path):
            print(file)
            if file[0:5].lower() == 'name':
                files.append(join(directory,root,file))
            else:
                files.append(join(directory,root,file))

for filetoopen in files:
    print(filetoopen)
    df = pd.concat([pd.read_excel(filetoopen, header=1)], ignore_index=True, sort=False)

我收到以下错误：

任何帮助将不胜感激，谢谢！

不支持的格式或文件损坏：预期的BOF记录
