对涉及列表中某些文件的过程进行循环？

Question

我有以下清单：

grouped_shapefiles在每个文件夹中有以下文件目录：（pst和dbound对）

[['C:\\Users\\user\\Desktop\\eff\\20194\\DBOUND\\DBOUND.shp',
  'C:\\Users\\user\\Desktop\\eff\\20194\\PST\\PST.shp'],
 ['C:\\Users\\user\\Desktop\\eff\\20042\\DBOUND\\DBOUND.shp',
  'C:\\Users\\user\\Desktop\\eff\\20042\\PST\\PST.shp'],
 ['C:\\Users\\user\\Desktop\\eff\\20161\\DBOUND\\DBOUND.shp',
  'C:\\Users\\user\\Desktop\\eff\\20161\\PST\\PST.shp'],
 ['C:\\Users\\user\\Desktop\\eff\\20029\\DBOUND\\DBOUND.shp',
  'C:\\Users\\user\\Desktop\\eff\\20029\\PST\\PST.shp'],
 ['C:\\Users\\user\\Desktop\\eff\\20008\\DBOUND\\DBOUND.shp',
  'C:\\Users\\user\\Desktop\\eff\\20008\\PST\\PST.shp']]

我想做一个for循环，在列表包含的每个文件夹（20194,20042,20161等…）的每个pst和dbound对的相应文件中执行这段代码

import geopandas as gpd
import pandas
#pst = gpd.read_file(r'C:\Users\user\Desktop\New folder1\PST')#this is not needed in the final because it takes the path by it self
#dbound = gpd.read_file(r'C:\Users\user\Desktop\New folder1\DBOUND')#same here
dbound.reset_index(inplace=True)
wdp = gpd.sjoin(pst, dbound, how="inner", op='within')#each dbound and pst from every folder
wdp['DEC_ID']=wdp['index']

我只想知道如何创建for循环，它将执行应该执行的文件中的代码。我试过for循环和使用括号中的位置，但没有达到应有的效果

不确定我是否正确理解了您的问题，您是否正在尝试成对地遍历列表中的项？如果是这样的话，那就很直截了当了：

for i in grouped_shapefiles:
    pst = gpd.read_file(i[0])
    dbound = gpd.read_file(i[1])
    if i[0].split("\\")[-3] == i[1].split("\\")[-3]:
        dbound.reset_index(inplace=True)
        wdp = gpd.sjoin(pst, dbound, how="inner", op='within')
        wdp['DEC_ID'] = wdp['index']
    else:
        print ("Folder pairs mismatch")
