这段代码有两个问题：

1. 在第一行的`import os`和第二行的`import xlwt`之间需要加上换行符`\n`。
2. 在第3行的`excel_path`变量中，需要在路径末尾加上文件名，即`result.xls`，否则会报错。

修改后的代码如下：

import os
import xlwt
from win32com.client import Dispatch

path = r'D:\softwaredata\pythondata\Findvideo30zhen\n'  # 请替换为您的桌面路径
excel_path = os.path.join(path, 'result.xls')  # 添加文件名

# 创建Excel文件
workbook = xlwt.Workbook(encoding='utf-8')
worksheet = workbook.add_sheet('result')
worksheet.write(0, 0, '文件路径')

# 遍历文件夹
for root, dirs, files in os.walk('C:\\'):  # 请替换为您要查询的文件夹路径
    for file in files:
        if file.endswith('.avi'):
            full_path = os.path.join(root, file)
            try:
                dso = Dispatch('DSOFile.OleDocumentProperties')
                dso.Open(full_path)
                frame_rate = dso.SummaryProperties.FrameRate
                if frame_rate == '30.00':
                    row = worksheet.last_used_row + 1
                    worksheet.write(row, 0, full_path)
            except:
                continue

# 保存Excel文件
workbook.save(excel_path)
