在这个项目中,我们将编写一个自动化脚本,用于定期执行某项任务,比如发送邮件或者备份文件。这个项目将帮助你理解 os 和 smtplib 库的使用。
关键知识点:
文件操作的基本方法。
如何发送电子邮件。
定时任务的实现。
示例代码:
1 2 3 4 5 6 7 8 9 10 11 12 13 14
import smtplib from email.mime.text import MIMEText
defsend_email(): msg = MIMEText('Hello, this is a test email') msg['Subject'] = 'Test' msg['From'] = 'your_email@example.com' msg['To'] = 'recipient@example.com' with smtplib.SMTP('smtp.example.com', 587) as server: server.login('your_email@example.com', 'password') server.sendmail(msg['From'], [msg['To']], msg.as_string())

X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2)
model = RandomForestClassifier() model.fit(X_train, y_train) predictions = model.predict(X_test)
