Python - 创建 Pandas 索引的新视图
要创建Pandas索引的新视图，请使用方法。首先，导入所需的库-index.view()
import pandas as pd
创建熊猫索引-
index = pd.Index([50, 10, 70, 110, 90, 50, 110, 90, 30])
显示熊猫指数-
print("Pandas Index...\n",index)创建一个新视图-
res = index.view('uint8')显示新视图-
print("\nThe new view...\n",res)它具有相同的基本价值-
print("\nView for 0th index...\n",res[0])
print("\nView for 1st index...\n",res[1])示例
以下是代码-
import pandas as pd
#创建Pandas索引
index = pd.Index([50, 10, 70, 110, 90, 50, 110, 90, 30])
#显示Pandas索引
print("Pandas Index...\n",index)
#返回索引中的元素数
print("\nNumber of elements in the index...\n",index.size)
#返回数据的dtype
print("\nThe dtype object...\n",index.dtype)
#创建新视图
res = index.view('uint8')
#显示新视图
print("\nThe new view...\n",res)
#共享相同的基本价值
print("\nView for 0th index...\n",res[0])
print("\nView for 1st index...\n",res[1])输出结果这将产生以下输出-
Pandas Index... Int64Index([50, 10, 70, 110, 90, 50, 110, 90, 30], dtype='int64') Number of elements in the index... 9 The dtype object... int64 The new view...
