Does anyone have some suggestions for why I can't get this code to do what I want it to do? I'm trying to write a script that will save me several hours each week. I need to download 83 zip files, extract them, import them into ArcGIS Pro, and then run the files through a series of geoprocessing tools, and then compile the results. Right now I'm doing this manually, and I'd love to automate this process as much as possible.
I can use the following sn-p of code to download and extract one file. I can't seem to get it to work with a for loop though.
import requests, zipfile
from io import BytesIO
url = 'https://www.deq.state.mi.us/gis-data/downloads/waterwells/Alcona_WaterWells.zip'
filename = url.split('/')[-1]
req = requests.get(url)
zipfile = zipfile.ZipFile(BytesIO(req.content))
zipfile.extractall(r'C:\Users\UserName\Downloads\Water_Wells')
I have created a url list of all 83 urls. These don't change, and content is updated regularly. This for loop only returns the first county, just like the above sn-p of code. I'm only including a few of the files here.
url_list = ['https://www.deq.state.mi.us/gis-data/downloads/waterwells/Alcona_WaterWells.zip',
'https://www.deq.state.mi.us/gis-data/downloads/waterwells/Alger_WaterWells.zip',
'https://www.deq.state.mi.us/gis-data/downloads/waterwells/Allegan_WaterWells.zip']
for link in url_list:
filename = url.split('/')[-1]
req = requests.get(url)
zipfile = zipfile.ZipFile(BytesIO(req.content))
zipfile.extractall(r'C:\Users\UserName\Downloads\Water_Wells')
