Python Pandas - 建立一個既包含原始索引又包含名稱的 Series
要建立一個同時包含原始索引和名稱的 Series,請在 Pandas 中使用 index.to_series() 方法。首先,匯入所需的庫 -
import pandas as pd
建立 Pandas 索引
index = pd.Index(['Electronics','Accessories','Decor', 'Books', 'Toys'],name ='Products')
將索引轉換為 Series −
print("\nIndex to series...\n",index.to_series())示例
以下是程式碼 −
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())輸出
這將產生以下輸出 −
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
