Python Pandas - 返回索引中的所有元素是否均为 True


要返回索引中的所有元素是否都为 True,请在 Pandas 中使用 index.all() 方法。

首先,导入所需的库 −

import pandas as pd

创建索引 −

index = pd.Index([15, 25, 35, 45, 55])

显示索引 −

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

如果索引中的所有元素都为 True 则返回 True −

print("\nCheck whether all elements are True...\n",index.all())

示例

以下是代码 −

import pandas as pd

# Creating the index
index = pd.Index([15, 25, 35, 45, 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 all the elements in the index are True
print("\nCheck whether all elements are True...\n",index.all())

输出

这将生成以下代码 −

Pandas Index...
Int64Index([15, 25, 35, 45, 55], dtype='int64')

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

Number of elements in the index...
5

Check whether all elements are True...
True
