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
