Python Pandas - 传回用于对索引进行排序的整数索引
如欲返回用于对索引进行排序的整数索引,请在 Pandas 中使用 index.argsort() 方法。首先,导入所需的函数库 −
import pandas as pd
创建 Pandas 索引 −
index = pd.Index(['Electronics','Accessories','Decor', 'Books', 'Toys'], name ='Products')
显示 Pandas 索引 −
print("Pandas Index...\n",index)传回用于对索引进行排序的整数索引 −
res = index.argsort()
范例
以下为代码 −
import pandas as pd
# Creating Pandas index
index = pd.Index(['Electronics','Accessories','Decor', 'Books', 'Toys'], name ='Products')
# Display the Pandas index
print("Pandas Index...\n",index)
# Return the number of elements in the Index
print("\nNumber of elements in the index...\n",index.size)
# Return the dtype of the data
print("\nThe dtype object...\n",index.dtype)
res = index.argsort()
# Return the integer indices that would sort the index
print("\nThe integer indices to sort the index...\n",res)
print("\nOrdered..\n",index[res])输出
这将产生以下输出 −
Pandas Index... Index(['Electronics', 'Accessories', 'Decor', 'Books', 'Toys'], dtype='object', name='Products') Number of elements in the index... 5 The dtype object... object The integer indices to sort the index... [1 3 2 0 4] Ordered.. Index(['Accessories', 'Books', 'Decor', 'Electronics', 'Toys'], dtype='object', name='Products')
