How do I get started with AI coding?β
5-minute setup:
- Choose a tool (start with ChatGPT - free)
- Create account at chat.openai.com
- Try a simple prompt:
Write a Python function to calculate fibonacci numbers
with memoization. Include docstring and example usage. - Review the code - don't just copy-paste
- Test it in your environment
Next steps:
- Read our Getting Started Tutorial
- Learn prompt engineering
- Explore best practices
Is AI coding cheating?β
No! It's a modern development tool, just like:
- Stack Overflow (searching for solutions)
- IDE autocomplete (code suggestions)
- Documentation (looking up APIs)
- Code snippets (reusing patterns)
You still need to:
- β Understand the problem
- β Review the solution
- β Test thoroughly
- β Debug issues
- β Maintain the code
- β Explain it to your team
Analogy: Using a calculator isn't "cheating" at math. You still need to know what calculation to do and verify the result makes sense.
Reality: Developers using AI will replace those who don't.
Can I use AI for my job/school projects?β
Job: Usually YES, but:
- β Check your company policy
- β Don't share proprietary code with AI
- β Don't share customer data
- β You're responsible for code quality
- β Follow security best practices
School: It depends:
- β Likely not allowed for homework/exams (ask instructor)
- β Often okay for personal projects
- β Can use for learning concepts
- β οΈ Academic honesty policies vary
Pro tip: Be transparent. Ask your employer/instructor about their AI policy.
Will AI replace developers?β
Not anytime soon. Here's why:
AI is good at:
- β Generating boilerplate code
- β Explaining concepts
- β Debugging simple issues
- β Writing tests
- β Code transformations
- β Documentation
AI struggles with:
- β Understanding business requirements
- β System architecture decisions
- β Complex debugging
- β Stakeholder communication
- β Project management
- β Creative problem-solving
- β Code maintenance at scale
The future: AI is a power tool that amplifies developer capabilities. Developers who use AI effectively will be more valuable, not replaced.
Think of it like: Excel didn't replace accountants, it made them more productive.

Security Best Practicesβ
# β
DO
export API_KEY="xxx" # Environment variable
# .gitignore
.env
# β DON'T
API_KEY = "sk-xxx" # Hardcoded in code (commits to git!)
How do I handle API rate limits?β
Understanding Rate Limits:
OpenAI (Tier 1):
- 500 requests/minute
- 10,000 tokens/minute
Anthropic:
- Based on your plan
- 50-1000 requests/minute
Handling Strategies:
1. Exponential Backoffβ
import time
from openai import OpenAI, RateLimitError
client = OpenAI()
def call_with_retry(prompt, max_retries=5):
for attempt in range(max_retries):
try:
return client.chat.completions.create(
model="gpt-4o",
messages=[{"role": "user", "content": prompt}]
)
except RateLimitError:
if attempt == max_retries - 1:
raise
wait_time = 2 ** attempt # 1s, 2s, 4s, 8s, 16s
print(f"Rate limit hit. Waiting {wait_time}s...")
time.sleep(wait_time)
2. Rate Limiterβ
from time import time, sleep
class RateLimiter:
def __init__(self, requests_per_minute=50):
self.rpm = requests_per_minute
self.timestamps = []
def wait_if_needed(self):
now = time()
# Remove old timestamps (>1 minute ago)
self.timestamps = [t for t in self.timestamps if now - t < 60]
# If at limit, wait
if len(self.timestamps) >= self.rpm:
sleep_time = 60 - (now - self.timestamps[0])
print(f"Rate limit approaching. Waiting {sleep_time:.1f}s...")
sleep(sleep_time)
self.timestamps.append(now)
# Usage
limiter = RateLimiter(requests_per_minute=50)
for task in tasks:
limiter.wait_if_needed()
result = api_call(task)
3. Batch Processingβ
# Process in smaller batches
def process_in_batches(items, batch_size=10, delay=1):
results = []
for i in range(0, len(items), batch_size):
batch = items[i:i+batch_size]
for item in batch:
results.append(process(item))
# Wait between batches
if i + batch_size < len(items):
time.sleep(delay)
return results
What if the AI gives wrong code?β
It happens! Here's what to do:
1. Debugging Workflowβ
Step 1: Copy error back to AI
"I got this error when running your code:
[paste error message]
From this code:
[paste code]
Please fix it and explain what was wrong."
Step 2: Test the fix
- Don't just replace code
- Understand what changed
- Verify the fix makes sense
Step 3: Learn the pattern
"What category of error is this?
How can I prevent it in the future?
What should I watch for?"
2. Improve Your Promptβ
# β Vague
"Write a function to process data"
# β
Specific
"Write a Python function to process CSV data:
- Handle missing values (fill with 0)
- Remove duplicate rows
- Convert date strings to datetime objects
- Handle encoding errors (use utf-8-sig)
- Include error handling for corrupt files
- Return pandas DataFrame
- Include docstring and type hints
- Include example usage"
3. Ask for Alternativesβ
"The code you generated has a bug with [specific issue].
Show me 2 different approaches to solve this."
4. Verify with Testsβ
# Always write tests for AI-generated code
def test_ai_generated_function():
# Happy path
assert process([1, 2, 3]) == [2, 4, 6]
# Edge cases
assert process([]) == []
assert process([0]) == [0]
# Error cases
with pytest.raises(TypeError):
process("not a list")
5. Use Multiple AIsβ
- Ask same question to ChatGPT and Claude
- Compare approaches
- Cross-validate solutions
Can I use AI offline?β
Options:
1. Local Models (Free)β
# Install Ollama
curl -fsSL https://ollama.com/install.sh | sh
# Run local models
ollama run codellama:13b
ollama run deepseek-coder:6.7b
# Use in code
from ollama import Client
client = Client()
response = client.generate(model='codellama', prompt='Write a function...')
Pros: Free, private, offline Cons: Slower, lower quality than GPT-4/Claude
2. Cache API Responsesβ
import json
import hashlib
class ResponseCache:
def __init__(self, cache_file='ai_cache.json'):
self.cache_file = cache_file
self.cache = self.load()
def load(self):
try:
with open(self.cache_file, 'r') as f:
return json.load(f)
except FileNotFoundError:
return {}
def save(self):
with open(self.cache_file, 'w') as f:
json.dump(self.cache, f)
def get(self, prompt):
key = hashlib.md5(prompt.encode()).hexdigest()
return self.cache.get(key)
def set(self, prompt, response):
key = hashlib.md5(prompt.encode()).hexdigest()
self.cache[key] = response
self.save()
# Usage
cache = ResponseCache()
def ask_ai(prompt):
# Check cache first
cached = cache.get(prompt)
if cached:
print("π¦ Using cached response")
return cached
# Call API if not cached
response = api_call(prompt)
cache.set(prompt, response)
return response

- Loading state
- Error handling
- Automatic retries (3 attempts)
- Cancellation on unmount
- TypeScript types
My existing code style:
[paste example]"
3. Show Examplesβ
β
"Generate tests in this format:
describe('add', () => {
it('should add two numbers', () => {
expect(add(2, 3)).toBe(5);
});
});
Now generate tests for [function]."
4. Request Explanationsβ
β
"Write the code and explain:
- Why you chose this approach
- What could go wrong
- How to extend it later"
5. Iterate and Refineβ
Iteration 1: "Explain concept X"

- Onboarding time: 1 week (-50%)
π Troubleshootingβ
Why is the AI not understanding my question?β
Common issues and fixes:
1. Too Vagueβ
β "Fix my code"
β
"I have a Python function that should sort a list,
but it's throwing a TypeError on line 15.
Here's the code: [paste]
Here's the error: [paste]
Expected: sorted list
Actual: TypeError"
2. Missing Contextβ
β
Always include:
- Language and version (Python 3.11)
- Framework and version (Django 4.2)
- What you've tried
- Full error message
- Expected vs actual behavior
3. Too Much at Onceβ
β "Build me a full social media app"
β
Break it down:
1. "Design database schema for users and posts"
2. "Create user authentication endpoints"
3. "Add post creation and retrieval"
4. [etc, step by step]
4. Assuming Knowledgeβ
β
"In my React app [describe architecture],
I have a component that [describe behavior].
When I [action], I expect [result] but get [actual].
Here's the relevant code:
[paste]
Tech stack:
- React 18.2
- TypeScript 5.0
- Redux Toolkit
- React Router 6"
The AI keeps generating similar wrong codeβ
Try these strategies:
1. Start Fresh Conversationβ
- AI has context from previous messages
- Starting new chat clears bad context
2. Be More Explicitβ
"Stop. The previous solutions all had [specific issue].
Instead, I need:
- [requirement 1]
- [requirement 2]
- [requirement 3]
Do NOT use [bad approach].
Instead use [better approach].
Show me pseudocode first before implementation."
3. Show Counterexampleβ
"You keep suggesting this:
[paste AI's suggestion]
But that won't work because [explain why].
I need a solution that handles [specific case].
Here's an example of what won't work and why:
[paste example]"
4. Ask for Alternativesβ
"Show me 3 completely different approaches to solve this:
1. [Approach A]
2. [Approach B]
3. [Approach C]
Explain pros/cons of each."
5. Try Different AIβ
- ChatGPT vs Claude often give different solutions
- One might understand your problem better
How do I handle errors in AI-generated code?β
Step-by-step debugging process:
## Step 1: Understand the Error
Don't just copy error to AI immediately.
- Read the error message
- Look at the stack trace
- Identify the line causing the error
- Think about what might be wrong
## Step 2: Try Quick Fixes
- Check for typos
- Verify imports
- Check variable names
- Review function signatures
## Step 3: Ask AI for Help
If still stuck, ask AI:
"I got this error in [language/framework]:
Error message:
[full error]
Code:
```[language]
[paste code]
Line that fails: [line number] What I've tried: [list attempts]
Expected behavior: [describe] Actual behavior: [describe]
Please:
- Explain the root cause
- Provide a fix with explanation
- Explain how to prevent this
- Suggest tests to add"
Step 4: Understand the Fixβ
Don't just apply the fix:
- Read the explanation
- Understand why it was broken
- Understand why fix works
- Learn the pattern
Step 5: Prevent Future Issuesβ
- Add error handling
- Add validation
- Write tests
- Document edge cases
