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
