Code Examples from Key Categories

Below are starter snippets illustrating libraries from different awesome-python categories. Each represents the entry point for that ecosystem according to the repository's curated list.

Data Processing with Pandas

import pandas as pd

# Load a CSV from a URL and compute a simple aggregate

url = "https://raw.githubusercontent.com/mwaskom/seaborn-data/master/iris.csv"
df = pd.read_csv(url)

# Group by species and compute mean sepal length

means = df.groupby("species")["sepal_length"].mean()
print(means)

Machine Learning with Scikit-learn

from sklearn.datasets import load_iris
from sklearn.model_selection import train_test_split
from sklearn.ensemble import RandomForestClassifier
from sklearn.metrics import accuracy_score

X, y = load_iris(return_X_y=True)
X_train, X_test, y_train, y_test = train_test_split(X, y, random_state=42)

clf = RandomForestClassifier(n_estimators=100, random_state=42)
clf.fit(X_train, y_train)

pred = clf.predict(X_test)
print("Accuracy:", accuracy_score(y_test, pred))

Web Development with FastAPI

from fastapi import FastAPI

app = FastAPI()

@app.get("/hello/{name}")
async def greet(name: str):
    return {"message": f"Hello, {name}!"}

Run with uvicorn this_file:app --reload.

Testing with Pytest

# test_math.py

def add(a, b):
    return a + b

def test_add():
    assert add(2, 3) == 5
    assert add(-1, 1) == 0

Execute with pytest -q.

Agentic AI with LangChain

from langchain.llms import OpenAI
from langchain.agents import initialize_agent, Tool

# Define a simple "search" tool

def echo_tool(query: str) -> str:
    return f"You asked: {query}"

tools = [Tool(name="Echo", func=echo_tool, description="Echoes the user query")]

agent = initialize_agent(
    tools,
    OpenAI(temperature=0),
    agent="zero-shot-react-description",
    verbose=True,
)

response = agent.run("What is the capital of France?")
print(response)
