25 个很棒的 Python 脚本合集（迷你项目） - PDF 下载

在本教程中，我编译了 25 个 Python 程序的集合。我已经包含链接以了解有关每个脚本的更多信息，例如packages installation和how to execute script?。

（公众号不能超链接到站外，文末有完整版PDF下载免费赠送）

1.将 JSON 转换为 CSV

import jsonif __name__ == '__main__':    try:        with open('input.json', 'r') as f:            data = json.loads(f.read())        output = ','.join([*data[0]])        for obj in data:            output += f'\n{obj["Name"]},{obj["age"]},{obj["birthyear"]}'        with open('output.csv', 'w') as f:            f.write(output)    except Exception as ex:        print(f'Error: {str(ex)}')

2.密码生成器

import randomimport stringtotal = string.ascii_letters + string.digits + string.punctuationlength = 16password = "".join(random.sample(total, length))print(password)

3.从多个文件中搜索字符串

​​​​​​​

import ostext = input("input text : ")path = input("path : ")# os.chdir(path)def getfiles(path):    f = 0    os.chdir(path)    files = os.listdir()    # print(files)    for file_name in files:        abs_path = os.path.abspath(file_name)        if os.path.isdir(abs_path):            getfiles(abs_path)        if os.path.isfile(abs_path):            f = open(file_name, "r")            if text in f.read():                f = 1                print(text + " found in ")                final_path = os.path.abspath(file_name)                print(final_path)                return True    if f == 1:        print(text + " not found! ")        return Falsegetfiles(path)

4.从给定网页获取所有链接

import requests as rqfrom bs4 import BeautifulSoupurl = input("Enter Link: ")if ("https" or "http") in url:    data = rq.get(url)else:    data = rq.get("https://" + url)soup = BeautifulSoup(data.text, "html.parser")links = []for link in soup.find_all("a"):    links.append(link.get("href"))# Writing the output to a file (myLinks.txt) instead of to stdout# You can change 'a' to 'w' to overwrite the file each timewith open("myLinks.txt", 'a') as saved:    print(links[:10], file=saved)

5.图像水印
