Key Steps in a Data Science Workflow

1. Data Collection:

Use libraries like BeautifulSoup for web scraping or APIs for fetching structured data.

2. Data Cleaning and Analysis:

Use Pandas for handling missing values and transforming data.

Visualize data patterns with Matplotlib and Seaborn.

3. Model Building:

Train machine learning models using Scikit-learn for classification, regression, or clustering.

4. Evaluation and Deployment:

Evaluate models using metrics like accuracy or precision-recall.

Deploy models using frameworks like Flask or FastAPI.

Getting Started

Here’s a simple Python snippet for a linear regression model using Scikit-learn:

from sklearn.linear_model import LinearRegression

from sklearn.model_selection import train_test_split

import pandas as pd

# Load your dataset

data = pd.read_csv('data.csv')

X = data[['feature1', 'feature2']] # Independent variables

y = data['target'] # Dependent variable

# Split the data

X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)

# Train the model

model = LinearRegression()

model.fit(X_train, y_train)

# Evaluate

print("Model accuracy:", model.score(X_test, y_test))
