使用urllib请求数据，携带中文参数，出现如上错误。  
解决办法：

import urllib.parse
    import string
    #将包含汉字的网址进行转译
    encode_new_url = urllib.parse.quote(final_url,safe=string.printable)
    print(encode_new_url)
    # 使用代码发送网络请求
    response = urllib.request.urlopen(encode_new_url)

加入以上代码即可，使用urllib将中文参数编码。  
最终程序如下：

import urllib.request
    import urllib.parse
    import string
    
    
    def get_method_params():
    
        url = "http://www.baidu.com/s?wd="
        #拼接字符串(汉字)
        #python可以接受的数据
        #https://www.baidu.com/s?wd=%E7%BE%8E%E5%A5%B3
    
        name = "美女"
        final_url = url+name
        print(final_url)
        #代码发送了请求
        #网址里面包含了汉字;ascii是没有汉字的;url转译
        #将包含汉字的网址进行转译
        encode_new_url = urllib.parse.quote(final_url,safe=string.printable)
        print(encode_new_url)
        # 使用代码发送网络请求
        response = urllib.request.urlopen(encode_new_url)
        # response = urllib.request.urlopen(final_url)
        print(response)
        #读取内容
        data = response.read().decode()
        print(data)
        #保存到本地
        with open("02-encode.html","w",encoding="utf-8")as f:
            f.write(data)
        # UnicodeEncodeError: 'ascii' codec can't encode
        # characters in position 10-11: ordinal not in range(128)
        #python:是解释性语言;解析器只支持 ascii 0 - 127
        #不支持中文
    
    get_method_params()
