Problem-Solving in Programming: Web Development and Data Science

Here's a summary of the key points about problem-solving in programming, focusing on web development and data science in Python:

1. Understand the Problem

  • Read problem statement.
  • Define objectives.
  • List inputs.
  • Identify constraints.
  • Consider edge cases.
    • Extremes.
    • Invalid inputs.
    • Uncommon scenarios.

2. Break It Down

  • Decompose into tasks.
    • Identify sub-tasks.
    • Group related tasks.
  • Order tasks logically.
    • Based on dependencies.
    • Sequentially.
  • Prioritize based on dependencies.
    • Critical path analysis.
    • Task interdependencies.

3. Write Down Your Solution

  • Outline high-level steps.
    • Pseudocode.
    • Flowchart.
  • Define data structures.
    • Data types.
    • Variables.
    • Data storage.
  • Plan algorithms.
    • Select algorithm.
    • Define algorithm steps.
    • Optimize if necessary.

4. Translate Your Solution to Code

  • Write code step by step.
    • Break into functions/methods.
    • Follow structure.
    • Implement logic.
  • Follow coding conventions.
    • Naming.
    • Style.
    • Formatting.
  • Maintain readability.
    • Use comments.
    • Organize code.

5. Test Your Code

  • Create test cases.
    • Positive cases.
    • Negative cases.
    • Boundary conditions.
  • Cover various scenarios.
    • Exception handling.
    • Stress testing.
  • Execute tests.
    • Automated testing.
    • Manual testing.
    • Regression testing.
  • Verify expected outcomes.
    • Compare actual results.

6. Debug Failed Cases

  • Identify error sources.
    • Logs.
    • Stack traces.
  • Use debugging tools.
    • Breakpoints.
    • Watches.
    • Profilers.
  • Analyze logs.
    • Debugging messages.
    • Timing issues.

7. Move On to the Next Problem

  • Progress to the next task.
    • Prioritize.
    • Plan.
  • Test completed tasks.
    • Cross-check.
    • Re-test.
    • Validate fixes.
  • Document issues.
    • Detailed bug reports.
    • Known problems.
  • Note lessons learned.
    • Continuous improvement.
    • Knowledge sharing.
