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
