[問題] DataFrame replace "-" None 問題

目標 想讓"," 換成空值

無法直接replace None (沒反應)

用了np.nan型態會變成float (我要int)

請指教謝謝 附上代碼

import pandas as pd
df = pd.DataFrame({'A': [',', 2], 'B': [0, 2]},)
df
df.replace(",",None)
df.replace(",",pd.np.nan)['A']

推 ANIO1021: 用re取代看看
推 skyconquer: 試試這個: df.replace(",", pd.NA)
