AI and Python Code Snippets:
1. Simple Linear Regression:
from sklearn.linear_model import LinearRegression import numpy as np X = np.array([[1], [2], [3], [4]]) y = np.array([2, 4, 6, 8]) model = LinearRegression() model.fit(X, y) print(model.predict([[5]]))
Predict values using linear regression.
2. Data Visualization with Matplotlib:
import matplotlib.pyplot as plt
x = [1, 2, 3, 4]
y = [10, 20, 25, 30]
plt.plot(x, y)
plt.xlabel('X-axis')
plt.ylabel('Y-axis')
plt.title('Simple Line Graph')
plt.show()
Create a simple line graph.
3. File Handling in Python:
with open('example.txt', 'r') as file:
content = file.read()
print(content)
Read and print the contents of a file.
4. Basic Web Scraping with BeautifulSoup:
from bs4 import BeautifulSoup import requests url = 'https://example.com' response = requests.get(url) soup = BeautifulSoup(response.text, 'html.parser') print(soup.title.text)
Scrape the title of a webpage.
5. Automate Tasks with Cron (Linux):
crontab -e
