使用熊猫查询具有多词标题的列

If you use this code, you can get all rows with bar in A

import pandas as pd
 df = pd.DataFrame({'A': 'foo bar foo bar foo bar foo foo'.split(),
                   'B': 'one one two three two two one three'.split()})
 print(df)
print("=============")
print( df.query('A== "bar"') )

WSo when I use this code, I expect to get all rows with bar in A thing but I get an error.

import pandas as pd
 df = pd.DataFrame({'A thing': 'foo bar foo bar foo bar foo foo'.split(),
                   'B thing': 'one one two three two two one three'.split()})
 print(df)
print("=============")
print( df.query('A thing== "bar"') )

有没有一种方法可以处理列名称中的空格？
