How do I find and remove duplicate rows in pandas? How do I avoid a SettingWithCopyWarning in pandas? How do I change display options in pandas? How do I create a pandas DataFrame from another object? How do I apply a function to a pandas Series or DataFrame? In [1]: # 传统方式...
In Example 1, I’ll explain how to exchange the infinite values in a pandas DataFrame by NaN values.This also needs to be done as first step, in case we want to remove rows with inf values from a data set (more on that in Example 2)....
df_add_ex = pd.DataFrame(['123 MAIN St Apartment 15', '123 Main Street Apt 12 ', '543 FirSt Av', ' 876 FIRst Ave.'], columns=['address']) df_add_ex 1. 2. 3. 我们可以看到,地址特征非常混乱。 如何处理地址不一致的数据?
# there were duplicate rows print(df.shape) print(df_dedupped.shape) 我们发现,有 10 行是完全复制的观察值。 如何处理基于所有特征的复制数据? 删除这些复制数据。 复制数据类型 2:基于关键特征 如何找出基于关键特征的复制数据? 有时候,最好的方法是删除基于一组唯一标识符的复制数据。 例如,相同使用面积、...
