Python是一種功能強大的程式語言,被廣泛應用於資料分析、人工智慧、網站開發等各個領域。它具有簡潔易讀的語法和豐富的函式庫,讓程式設計變得簡單有效率。若想更掌握Python,開啟自己的創新之旅,不妨嘗試一些具體的程式碼範例。
import pandas as pd import matplotlib.pyplot as plt data = {'Name': ['Alice', 'Bob', 'Cathy', 'David'], 'Age': [25, 30, 35, 40]} df = pd.DataFrame(data) plt.bar(df['Name'], df['Age']) plt.xlabel('Name') plt.ylabel('Age') plt.title('Age Distribution') plt.show()
import requests from bs4 import BeautifulSoup url = 'http://example.com' response = requests.get(url) soup = BeautifulSoup(response.content, 'html.parser') print(soup.prettify())
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 iris = load_iris() X, y = iris.data, iris.target X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42) model = RandomForestClassifier() model.fit(X_train, y_train) predictions = model.predict(X_test) print('Accuracy:', accuracy_score(y_test, predictions))
透過這些簡單的範例,你可以體驗Python在資料分析、網路爬
