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输出结果# Creating Pandas index
index = pd.Index(['Electronics','Accessories','Decor', 'Books', 'Toys'], name ='Products')
# Display the Pandas index
print("Pandas Index...\n",index)
# Return the number of elements in the Index
print("\nNumber of elements in the index...\n",index.size)
# Return the dtype of the data
print("\nThe dtype object...\n",index.dtype)
# replace values where condition is False
# Here, except the 'Decor', every other element gets replaced
print("\nReplace index vales where condition is False...\n",index.where(index.isin(['Decor']), 'Miscellaneous'))
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')
