Python Pandas – 返回索引中是否存在任何元素为True的情况

要返回索引中所有元素是否都为True，请使用Pandas中的 index.any() 方法。

首先，导入所需的库 −

import pandas as pd

创建具有一些True（非零）和False（零）元素的索引 −

index = pd.Index([15, 25, 0, 0, 55])

显示索引 −

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

如果索引中存在任何元素为True，则返回True ：−

print("\n检查索引中是否存在任何元素为True的情况...\n",index.any())

示例

以下是代码−

import pandas as pd

# Creating the index with some True (non-zero) and False (zero) elements
index = pd.Index([15, 25, 0, 0, 55])

# Display the index
print("Pandas Index...\n",index)

# Return a tuple of the shape of the underlying data
print("\nA tuple of the shape of underlying data...\n",index.shape)

# Return the number of elements in the Index
print("\nNumber of elements in the index...\n",index.size)

# Return True if any element in the index is True
print("\nCheck whether any element in the index is True...\n",index.any())

输出

这将产生以下输出−

Pandas Index...
Int64Index([15, 25, 0, 0, 55], dtype='int64')

A tuple of the shape of underlying data...
(5,)

Number of elements in the index...
5

Check whether any element in the index is True...
True
