我的数据框df中有以下列:
df.dtypes
MeanTemperatureC int64
MaxTemperatureC float64
MinTemperatureC int64
DewPointC int64
MeanDewPointC int64
MinDewpointC int64
MaxHumidity int64
MeanHumidity int64
MinHumidity int64
MaxSeaLevelPressurehPa int64
MeanSeaLevelPressurehPa float64
MinSeaLevelPressurehPa int64
MaxVisibilityKm int64
MeanVisibilityKm float64
MinVisibilitykM float64
MaxWindSpeedKm/h int64
MeanWindSpeedKm/h int64
MeanTemperatureCT category
dtype: object
我想将列'MeanTemperatureCT'的数据类型更改为str。 我已经尝试了以下内容:
df['MeanTemperatureCT'].astype(np.str)
并没有改变数据类型。所以,请帮忙。
答案 0 :(得分:5)
df['MeanTemperatureCT']= df['MeanTemperatureCT'].astype(str)
