Я хочу заменить значения фрейма данных столбца, если они находятся в списке. Итак, я попробовал:
to_remove = ['Name (Optional)', 'Date of Birth',
'Please enter your phone number.']
df_merged['Section'].map({to_remove: None})
Но вернулся:
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-820-a080ccbc0440> in <module>
----> 1 df_merged['Section'].map({to_remove: None})
TypeError: unhashable type: 'list'
Обновление
Я попробовал:
df_merged['Section'].map({k: None for k in to_remove})
Но, похоже, только обработать обратно NaN:
0 NaN
1 NaN
2 NaN
3 NaN
4 NaN
5 NaN
