What's the best way to download a file to disk using Python3? or How can I download a file to disk wi - darkNomad77 - 15-02-2025
"Python3 download file to disk – what’s the simplest method?"
hey folks!
i’m trying to figure out the easiest way to do a python3 download file to disk thing. like, just grab a file from a URL and save it locally.
i’ve seen a bunch of ways (urllib, requests, etc.), but what’s the *simplest*? don’t need anything fancy, just reliable.
also, any gotchas i should watch out for? like, permissions or weird errors?
thx in advance!
(ps: if u got code snippets, even better. lazy dev here 😅)

The simplest way for python3 download file to disk is using `requests`. Just install it (`pip install requests`) and use this snippet:
```python
import requests
url = "https://example.com/file.zip"
response = requests.get(url)
with open("file.zip", "wb") as f:
f.write(response.content)
```
Watch out for HTTP errors—add `response.raise_for_status()` to catch bad responses. Also, check disk permissions!

urllib works too if you don’t wanna install extra stuff. Here’s how:
```python
from urllib.request import urlretrieve
url = "https://example.com/file.zip"
urlretrieve(url, "file.zip")
```
Super short, but less flexible than `requests`. Also, urllib might throw weird errors on redirects or timeouts, so be ready for that.

If you’re lazy (like me 😆), just use `wget` via subprocess:
```python
import subprocess
url = "https://example.com/file.zip"
subprocess.run(["wget", url])
```
Not pure python3 download file to disk, but it’s one line and works everywhere wget is installed.

For a modern approach, try `httpx`—it’s like `requests` but async-ready.
```python
import httpx
url = "https://example.com/file.zip"
with httpx.Client() as client:
r = client.get(url)
with open("file.zip", "wb") as f:
f.write(r.content)
```
Bonus: handles HTTP/2 and is super fast. Downside? Another dep to install.

Don’t forget error handling! Here’s a robust python3 download file to disk snippet with `requests`:
```python
import requests
from pathlib import Path
url = "https://example.com/file.zip"
save_path = Path("file.zip")
try:
r = requests.get(url, timeout=10)
r.raise_for_status()
save_path.write_bytes(r.content)
except Exception as e:
print(f"Oops: {e}")
```
This catches timeouts, bad URLs, and write errors.

If you’re on Windows, watch out for antivirus blocking downloads!
I’ve had cases where python3 download file to disk just... silently fails. Temporarily disabling AV or adding exclusions helps.
Also, `requests` is king, but `urllib` is built-in. Tradeoffs!

For big files, use streaming to avoid memory issues:
```python
import requests
url = "https://example.com/bigfile.zip"
with requests.get(url, stream=True) as r:
r.raise_for_status()
with open("bigfile.zip", "wb") as f:
for chunk in r.iter_content(chunk_size=8192):
f.write(chunk)
```
This saves RAM by writing chunks instead of loading everything at once.

yo thanks everyone!
tried the `requests` method first and it worked like a charm.
one q tho—how do i handle like... super slow downloads? the script just hangs sometimes. is there a way to add a progress bar or timeout?
also, big shoutout for the streaming tip—didn’t even think about memory issues.
(ps: windows AV is indeed a pain, had to whitelist my script folder 😑)

If you’re dealing with auth or cookies, `requests` is way easier than `urllib`.
```python
import requests
url = "https://example.com/private_file.zip"
cookies = {"session": "123abc"}
headers = {"User-Agent": "Mozilla/5.0"}
r = requests.get(url, cookies=cookies, headers=headers)
with open("file.zip", "wb") as f:
f.write(r.content)
```
Headers/cookies make `requests` worth the extra install.
