如何使用 pandas 数据框作为参考制作路径

Question

我计划在数百个文件夹中使用 Excel 制作数百个数据框。

引用table:

        Folder                         Category           Sub Category
205     News and Media                 News and Media     News and Media
206     Vehicles - Motorcycles         Vehicles           Motorcycles
207     Vehicles - Motorsports         Vehicles           Motorsports
208     Vehicles - Other Vehicles      Vehicles           Other Vehicles

代码示例：

Data_Vehicles-Motorcycles = pd.read_excel('[Folder]/TopSites-Vehicles_Motorcycles-(999)-(2022_03).xlsx','Aggregated_Data_for_Time_Period')

模式

Data_[Folder] = pd.read_excel('[Folder]/TopSites-[Category]_[Sub Category]-(999)-(2022_03).xlsx','Aggregated_Data_for_Time_Period')

备注

我知道文件夹名称使用 space，但我只想使用文件夹名称中的单词保存数据框，无论是正则表达式还是清理

Answer 1

首先在您的数据框中创建一个名为“Path”的列。

df['Path'] = df['Folder'] + '/TopSites-' + df['Category'] + '_' + df['Sub Category'] + '-(999)-(2022_03).xlsx' # Create the whole path

之后，您可以遍历数据框并读取每条路径。

for path in df['Path']:
    folder = path.split('/')[0] # Get the folder from the path
    Data_[folder] = pd.read_excel(path)
