要从原始索引创建 DataFrame 但强制执行新索引,请使用. 将参数索引设置为False。index.to_frame()
首先,导入所需的库 -
import pandas as pd
创建熊猫索引 -
index = pd.Index(['Electronics','Accessories','Decor', 'Books', 'Toys'],name ='Products')
显示 Pandas 索引
print("Pandas Index...\n",index)
强制执行新索引并将索引转换为 DataFrame。在这里,实际索引被另一个索引替换 -
print("\nIndex to DataFrame...\n",index.to_frame(index=False))
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) # Enforce new index and convert index to DataFrame # Here, the actual index gets replaced by another index print("\nIndex to DataFrame...\n",index.to_frame(index=False))输出结果
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 DataFrame... Products 0 Electronics 1 Accessories 2 Decor 3 Books 4 Toys
