The nntplib module implements NNTP (Network News Transfer Protocol) client functionality for accessing Usenet newsgroups.
Complexity Reference¶
| Operation | Time | Space | Notes |
|---|---|---|---|
connect() |
O(1) | O(1) | Network connection |
| List groups | O(n) | O(n) | n = newsgroups |
| Get articles | O(n) | O(n) | n = articles |
Accessing Newsgroups¶
Basic NNTP Operations¶
import nntplib
# Connect - O(1)
nntp = nntplib.NNTP('news.example.com')
# Get article - O(1)
code, num, id, lines = nntp.article('<message-id>')
print(lines)
# Group info - O(1)
code, count, first, last, name = nntp.group('comp.lang.python')
print(f"Group: {name}, Articles: {count}")
# List articles - O(n)
code, num, first, last, name = nntp.group('comp.lang.python')
code, articles = nntp.over((first, last))
for article_num, headers in articles:
print(f"{article_num}: {headers['subject']}")
# Disconnect - O(1)
nntp.quit()
