In the project, 'houses' is the source data, which contains multiple dtypes like 'float/int', 'object'.
With houses.dtypes
methods, we got following:
Order int64
PID int64
MS SubClass int64
MS Zoning object
Lot Frontage float64
Lot Area int64
Street object
... ...
Actually, I wanna locate the numeric columns in 'houses', thus I used this code:
houses_numeric = houses[(houses.dtypes=='int64')|(houses.dtypes=='float64')]
Finally, I got the IndexError:
IndexingError Traceback (most recent call last)
<ipython-input-50-33e1ea213da1> in <module>()
----> 1 houses_numeric = houses[(houses.dtypes=='int64')|(houses.dtypes=='float64')]
2 #(houses.dtypes=='int64')|(houses.dtypes=='float64')
3 #houses[(houses.dtypes=='int64')|(houses.dtypes=='float64')]

Are there any hints to fix this error? Thanks!
