Python for AI: Complete Learning Path 2026
Bangalore, November 2024
I was interviewing candidates for an LLM Engineer position (₹35 LPA package).
Out of 47 applicants:
- 45 mentioned "Python" on resume
- 12 could write a basic function
- Only 3 could explain decorators or list comprehensions
- Only 1 got the job
The problem? Everyone "knows" Python. Few master it.
The difference between knowing and mastering Python = ₹12 LPA vs ₹35 LPA.
This comprehensive guide will take you from Python zero to AI job-ready in 8 weeks.
