How will you improve the performance of a program in Python?

There are many ways to improve the performance of a Python program. Some of these are as follows:

  1. Data Structure: We have to *select* the right data structure for our purpose in a Python program.
  2. Standard Library: Wherever possible, we should use methods from standard library. Methods implemented in standard library have much better performance than user implementation.
  3. Abstraction: At times, a lot of abstraction and indirection can cause slow performance of a program. We should remove the redundant abstraction in code.
  4. Algorithm: Use of right algorithm can make a big difference in a program. We have to find and select the suitable algorithm to solve our problem with high performance.
