这个怎么样:

df = DataFrame({"pear": [1,2,3], "apple": [2,3,4], "orange": [3,4,5]})
out = np.argwhere(df.columns.isin(['apple', 'orange'])).ravel()
print(out)
[1 2]

当列可能存在，也可能不存在时，下面的(来自上面的变体)可以工作。

ix = 'none'
try:
     ix = list(df.columns).index('Col_X')
except ValueError as e:
     ix = None  
     pass

if ix is None:
   # do something

DSM的解决方案是有效的，但是如果你想要一个直接等价的方法(df。Columns == name).nonzero()

这里有一个通过列表理解的解决方案。Cols是要获取索引的列的列表:

[df.columns.get_loc(c) for c in cols if c in df]
