要使用转换为dtypes的值创建索引,请使用Pandas中的方法。首先,导入所需的库-index.astype()
import pandas as pd创建熊猫索引-
index = pd.Index([50.4, 10.2, 70.5, 110.5, 90.8, 50.6])显示熊猫指数-
print("Pandas Index...\n",index)将数据类型转换为int64-
index.astype(int64)以下是代码-
import pandas as pd #创建Pandas索引 index = pd.Index([50.4, 10.2, 70.5, 110.5, 90.8, 50.6]) #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) #将数据类型转换为int64 print("\nIndex object after converting type...\n",index.astype(int64))输出结果这将产生以下输出-
Pandas Index... Float64Index([50.4, 10.2, 70.5, 110.5, 90.8, 50.6], dtype=float64) Number of elements in the index... 6 The dtype object... float64 Index object after converting type... Int64Index([50, 10, 70, 110, 90, 50], dtype=int64)
