Python - 检查 Pandas 索引是否仅包含布尔值
要检查 Pandas 索引是否仅包含布尔值,请在 Pandas 中使用index.is_boolean()方法。首先,导入所需的库 -
import pandas as pd
创建 Pandas 索引
index = pd.Index([True, True, False, False, True, True, True])
显示 Pandas 索引 -
print("Pandas Index...\n",index)
检查索引值是否只有布尔值 -
print("\nIndex values only consists of booleans?\n",index.is_boolean())
示例
以下是代码 -
import pandas as pd # Creating Pandas index index = pd.Index([True, True, False, False, True, True, True]) # 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) # check whether index values has only booleans print("\nIndex values only consists of booleans?\n",index.is_boolean())
输出
这将生成以下输出 -
Pandas Index... Index([True, True, False, False, True, True, True], dtype='object') Number of elements in the index... 7 The dtype object... object Index values only consists of booleans? True
