1. Use Built-in Functions & Libraries Python’s built-in functions (like sum(), map(), and zip()) are optimized in C and run much faster than manual loops. 2. Use List Comprehensions List comprehensions are much faster than loops for creating lists. 3. Use Generators Instead of Lists Generators don’t store all values in memory, making them more efficient. 4. Use NumPy for Numerical Operations If you're dealing with numbers, NumPy is much faster than Python’s built-in lists. 5. Avoid Unnecessary Loops Loops are slow in Python. Try using vectorized operations, built-in functions, or even multiprocessing. 6. Use multiprocessing or asyncio for Parallel Processing If your code is CPU-intensive, split tasks into multiple processes. 7. Use lru_cache for Function Memoization If a function gets called multiple times with the same arguments, caching can save time. 8. Use Cython or JIT Compilation (Numba) For performance-critical parts, you can compile Python to C using Cython or JIT (Just-In-Time) compile with Numba. 9. Profile Your Code Use Python’s built-in profiler to find bottlenecks. 10. Use PyPy Instead of CPython PyPy is an alternative Python interpreter that can make your code significantly faster in some cases. read less

It seems you want to work on Django Web Framework. The very first pre-requisite for this is that you must know Python Programming. So, I would say learn Python first before embarking on Django Web-Framework.

Which Python should I learn, Python 2.7 or 3.x?
Better to learn latest versions always. You cannot find much differences. If you learn one version remaining versions you can understand easily.
