以下是16个非常实用的Python脚本示例,每个脚本都有其特定的用途,并且我会附上相应的源码。这些脚本涵盖了数据处理、网络请求、文件操作等多个方面,非常适合初学者和进阶者学习和使用。
1. 批量重命名文件
import osdef batch_rename(folder_path, prefix):for filename in os.listdir(folder_path):old_file = os.path.join(folder_path, filename)new_file = os.path.join(folder_path, prefix + filename)os.rename(old_file, new_file)# 使用示例
folder_path = 'path/to/your/folder'
prefix = 'new_'
batch_rename(folder_path, prefix)
2. 发送HTTP GET请求
import requestsdef send_get_request(url):response = requests.get(url)return response.text# 使用示例
url = 'http://example.com'
print(send_get_request(url))
3. 读取CSV文件
import csvdef read_csv(file_path):with open(file_path, mode='r', encoding='utf-8') as file:csv_reader = csv.reader(file)for row in csv_reader:print(row)# 使用示例
file_path = 'path/to/your/file.csv'
read_csv(file_path)
4. 写入CSV文件
import csvdef write_csv(file_path, data):with open(file_path, mode='w', encoding='utf-8', newline='') as file:csv_writer = csv.writer(file)for row in data:csv_writer.writerow(row)# 使用示例
file_path = 'path/to/your/file.csv'
data = [['name', 'age'], ['Alice', 30], ['Bob', 25]]
write_csv(file_path, data)
5. 读取JSON文件
import jsondef read_json(file_path):with open(file_path, 'r', encoding='utf-8') as file:return json.load(file)# 使用示例
file_path = 'path/to/your/file.json'
data = read_json(file_path)
print(data)
6. 写入JSON文件
import jsondef write_json(file_path, data):with open(file_path, 'w', encoding='utf-8') as file:json.dump(data, file, ensure_ascii=False, indent=4)# 使用示例
file_path = 'path/to/your/file.json'
data = {'name': 'Alice', 'age': 30}
write_json(file_path, data)
7. 简单的网页爬虫
import requests
from bs4 import BeautifulSoupdef simple_web_crawler(url):response = requests.get(url)soup = BeautifulSoup(response.text, 'html.parser')titles = soup.find_all('title')for title in titles:print(title.text)# 使用示例
url = 'http://example.com'
simple_web_crawler(url)
8. 计算文件夹大小
import osdef calculate_folder_size(folder_path):total_size = 0for root, dirs, files in os.walk(folder_path):for file in files:file_path = os.path.join(root, file)total_size += os.path.getsize(file_path)return total_size# 使用示例
folder_path = 'path/to/your/folder'
print(f'Folder size: {calculate_folder_size(folder_path)} bytes')
9. 检查网站是否可访问
import requestsdef check_website_availability(url):try:response = requests.get(url)return response.status_code == 200except requests.ConnectionError:return False# 使用示例
url = 'http://example.com'
print(check_website_availability(url))
10. 简单的数据清洗(去除空格和换行符)
def clean_data(data):return [item.strip() for item in data if item.strip()]# 使用示例
data = [' Alice ', 'Bob\n', 'Charlie', '']
cleaned_data = clean_data(data)
print(cleaned_data)
11. 合并多个Excel文件
import pandas as pddef merge_excel_files(folder_path):merged_df = pd.DataFrame()for file in os.listdir(folder_path):if file.endswith('.xlsx'):file_path = os.path.join(folder_path, file)df = pd.read_excel(file_path)merged_df = pd.concat([merged_df, df], ignore_index=True)return merged_df# 使用示例
folder_path = 'path/to/your/excel/files'
merged_data = merge_excel_files(folder_path)
print(merged_data)
12. 提取PDF文件中的文本
import PyPDF2def extract_text_from_pdf(pdf_path):with open(pdf_path, 'rb') as file:pdf_reader = PyPDF2.PdfFileReader(file)text = ''for page_num in range(pdf_reader.numPages):page = pdf_reader.getPage(page_num)text += page.extractText()return text# 使用示例
pdf_path = 'path/to/your/file.pdf'
text = extract_text_from_pdf(pdf_path)
print(text)
13. 发送电子邮件
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipartdef send_email(sender_email, receiver_email, password, subject, body):message = MIMEMultipart()message['From'] = sender_emailmessage['To'] = receiver_emailmessage['Subject'] = subjectmessage.attach(MIMEText(body, 'plain'))server = smtplib.SMTP('smtp.gmail.com', 587)server.starttls()server.login(sender_email, password)text = message.as_string()server.sendmail(sender_email, receiver_email, text)server.quit()# 使用示例
sender_email = 'your_email@gmail.com'
receiver_email = 'receiver_email@gmail.com'
password = 'your_password'
subject = 'Test Email'
body = 'This is a test email.'
send_email(sender_email, receiver_email, password, subject, body)
14. 简单的文本加密和解密(使用Base64)
import base64def encrypt_text(text):return base64.b64encode(text.encode()).decode()def decrypt_text(encrypted_text):return base64.b64decode(encrypted_text).decode()# 使用示例
text = 'Hello, World!'
encrypted_text = encrypt_text(text)
print(f'Encrypted: {encrypted_text}')
decrypted_text = decrypt_text(encrypted_text)
print(f'Decrypted: {decrypted_text}')
15. 生成随机密码
import random
import stringdef generate_password(length):characters = string.ascii_letters + string.digits + string.punctuationreturn ''.join(random.choice(characters) for i in range(length))# 使用示例
password_length = 12
password = generate_password(password_length)
print(password)
16. 检查密码强度
python
def check_password_strength(password):strength = 0if len(password) >= 8:strength += 1if any(char.isdigit() for char in
