以下是各个库的简单示例代码：

ruamel.yaml.clib：自定义库，无法给出具体示例代码。

rpds-py：自定义库，无法给出具体示例代码。

regex：

import regex

text = "Hello, world!"
pattern = r"world"
matches = regex.findall(pattern, text)
print(matches)

rapidfuzz：

from rapidfuzz import fuzz

s1 = "Hello world"
s2 = "Hello there"
similarity = fuzz.ratio(s1, s2)
print(similarity)

PyYAML：

import yaml

data = {
   
   'name': 'John', 'age': 30}
with open('data.yaml', 'w') as file:
    yaml.dump(data, file)

with open('data.yaml', 'r') as file:
    loaded_data = yaml.load(file, Loader=yaml.FullLoader)
    print(loaded_data)

python-multipart：自定义库，无法给出具体示例代码。

python-magic：

import magic

file_path = "some_file.txt"
file_type = magic.from_file(file_path)
print(file_type)

python-iso639：自定义库，无法给出具体示例代码。

python-dotenv：

from dotenv import load_dotenv

load_dotenv()
import os

print(os.getenv('SOME_VARIABLE'
