Python Pandas - 返回索引中的所有元素是否为真

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

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 #创建索引 index = pd.Index([15, 25, 35, 45, 55]) #显示索引 print("Pandas Index...\n",index) #返回基础数据形状的元组 print("\nA tuple of the shape of underlying data...\n",index.shape) #返回索引中的元素数 print("\nNumber of elements in the index...\n",index.size) #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())输出结果

这将产生以下代码-

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
