Python Pandas - 创建一个既包含原始索引又包含名称的 Series
要创建一个同时包含原始索引和名称的 Series,请在 Pandas 中使用 index.to_series() 方法。首先,导入所需的库 -
import pandas as pd
创建 Pandas 索引
index = pd.Index(['Electronics','Accessories','Decor', 'Books', 'Toys'],name ='Products')
将索引转换为 Series −
print("\nIndex to series...\n",index.to_series())示例
以下是代码 −
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)
# convert index to series
print("\nIndex to series...\n",index.to_series())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 Index to series... Products Electronics Electronics Accessories Accessories Decor Decor Books Books Toys Toys Name: Products, dtype: object
