Python Security Tips

5 min read
Python security: use parameterised queries for databases, the secrets module for generating tokens, bcrypt for passwords, and subprocess with a list instead of shell=True. Run pip audit to find vulnerabilities.

Security Best Practices

  • Never hardcode secrets — use environment variables
  • Use secrets module for tokens, not random
  • Sanitize user inputs before database queries
  • Use parameterized queries, never f-strings in SQL
  • Keep dependencies updated: pip audit
  • Hash passwords with bcrypt or argon2, never MD5/SHA1
