Python Basics

Control Flow

Control flow statements let your AI agents make decisions and handle different scenarios.

If/Elif/Else

if condition:
    # do something
elif another_condition:
    # do something else
else:
    # fallback

For Loops

for item in collection:
    process(item)

While Loops

while condition:
    # keep going

Comprehensions

Pythonic one-liners:

# List comprehension
squares = [x**2 for x in range(10)]

# Dict comprehension  
word_lengths = {w: len(w) for w in words}

Try It Yourself

2response_type = "function_call"

4if response_type == "text":
5    print("Processing text response...")
6elif response_type == "function_call":
7    print("Executing function call...")
8elif response_type == "error":
9    print("Handling error...")
10else:
11    print("Unknown response type")

13# For loop - processing messages
14messages = [

16    {"role": "assistant", "content": "Hi there!"},

18]

20for msg in messages:
21    print(f"{msg['role'].upper()}: {msg['content']}")

23# While loop - retry logic
24max_retries = 3
25attempt = 0
26success = False
27
28while attempt < max_retries and not success:
29    attempt += 1
30    print(f"Attempt {attempt}...")
31    # Simulate success on third try
32    if attempt == 3:
33        success = True
34        print("Success!")

36# List comprehension - filter user messages
37user_messages = [m["content"] for m in messages if m["role"] == "user"]
38print(f"\nUser messages: {user_messages}")
