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())
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
