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

Electronics  Electronics
Accessories  Accessories
Decor              Decor
Books              Books
Toys                Toys
