成功解决 ValueError: Shape of passed values is (3, 1), indices imply (3, 3)

被这个问题影响太久了，今天一定要记录一下！

说到底，是自己学的不扎实，基本概念不牢靠，很多东西只知道用。

import pandas as pd
print(pd.DataFrame([1,2]))
print('------------------')
print(pd.DataFrame([[1,2]]))

运行结果如下：

可以看到，当是 [1,2]时，是一个列表，只有一维，相当于是：

print(pd.DataFrame([[1],[2]]))

当是 [[1,2]]时，有两个括号，算是二维：

print(pd.DataFrame([[1,2],[3,4]]))

当每个变量都是列表时，如果要达到二维的效果，就要再加一个括号：

data = pd.DataFrame([[index, uri_data_list, first_data]], columns=['index', 'uri_list', 'first_uri'])
