Python Pandas - 创建带有原始索引和名称的数据框
要创建同时带有原始索引和名称的数据框,请在 Pandas 中使用 **index.to_frame()** 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')
显示 Pandas 索引 -
print("Pandas Index...\n",index)将索引转换为数据框 -
print("\nIndex to DataFrame...\n",index.to_frame())示例
以下是代码内容 -
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 DataFrame
print("\nIndex to DataFrame...\n",index.to_frame())输出
将生成以下输出 -
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 DataFrame... Products Products Electronics Electronics Accessories Accessories Decor Decor Books Books Toys Toys
