要返回基础数据的维数,请使用index.ndim属性。
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)
获取数据的维度 -
print("\nReturn the dimensions...\n",index.ndim)
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) # 返回一个表示索引中数据的数组 print("\nArray...\n",index.values) # 返回基础数据形状的元组 print("\nA tuple of the shape of underlying data...\n",index.shape) # 获取数据中的字节 print("\nReturn the bytes...\n",index.nbytes) # 获取数据的维度 print("\nReturn the dimensions...\n",index.ndim)输出结果
这将产生以下代码 -
Pandas Index... Int64Index([15, 25, 35, 45, 55], dtype='int64') Array... [15 25 35 45 55] A tuple of the shape of underlying data... (5,) Return the bytes... 40 Return the dimensions... 1
