Python Pandas - 替换条件为 False 的索引值

要替换条件为False的索引值，请使用Pandas中的方法。首先，导入所需的库-index.isin()

import pandas as pd

创建熊猫索引-

index = pd.Index([Electronics,Accessories,Decor, Books, Toys], name =Products)

显示熊猫指数-

print("Pandas Index...\n",index)

替换条件为False的值。在这里，除了“装饰”之外，所有其他元素都会被替换-

print("\nReplace index vales where condition is False...\n",index.where(index.isin([Decor]), Miscellaneous))

示例

以下是代码-

import pandas as pd #CreatingPandasindex index = pd.Index([Electronics,Accessories,Decor, Books, Toys], name =Products) #DisplaythePandasindex print("Pandas Index...\n",index) #ReturnthenumberofelementsintheIndex print("\nNumber of elements in the index...\n",index.size) #Returnthedtypeofthedata print("\nThe dtype object...\n",index.dtype) #replacevalueswhereconditionisFalse # Here, except the Decor, every other element gets replaced print("\nReplace index vales where condition is False...\n",index.where(index.isin([Decor]), Miscellaneous))输出结果

这将产生以下输出-

Pandas Index... Index([Electronics, Accessories, Decor, Books, Toys], dtype=object, name=Products) Number of elements in the index... 5 The dtype object... object Replace index vales where condition is False... Index([Miscellaneous, Miscellaneous, Decor, Miscellaneous,Miscellaneous],dtype=object, name=Products)
