使用正则表达式可以轻松完成此操作。但是，看来您是python新手。因此，以下更正的代码可能会帮助您。

import json
username = "jose"
email = "some_email"
password = "1234"

url = "some_url"

payload = json.dumps({"username": username,"email":email,"password":password},indent=4)
headers = { ''Content-Type'': ''application/json''}

response = requests.request("POST",url,headers=headers,data=payload)

print(response.text.encode(''utf8''))

根据您的问题，我会执行此功能

myweb=[]
while True:
    mywebsite=input("what is your favorite website?")
    if mywebsite=="done":
        print(myweb)
        break
    else:
        myweb.append(mywebsite)
        continue

# allocating enough space
mywebsite = [0]*len(myweb)

# extract it
for i in range(len(myweb)):
    # split based on www.domain.com
    mywebsite[i] = myweb[i].split(''.'')[1]

print(mywebsite)

在列表中的每个项目上使用正则表达式

>>> import re
>>> website = ''www.amazon.com''
>>> website = re.search(''www\.(.*)\.com'',website).group(1)
>>> website
''amazon''

如果所有输入的模式都是www.SOME_WEB_SITES.com，那么您可以使用

w2

还要考虑子域的情况，例如：

www.a.com->一个

www.a.b.com-> a.b

N = 3

w2 = Window.partitionBy(''product'',''specialty'').orderBy(''date'').rowsBetween(-N+1,0)

df_new = df2.select("*",F.round(F.sum(''sales'').over(w2)/N,2).alias(f''{N}month_avg_sales''))

您使用python字符串.strip()函数执行此操作。

myweb=[]
while True:
    mywebsite=input("what is your favorite website?")
    if mywebsite=="done":
        for x in myweb:
            print(x.strip("www." + ".com")) #Strips www. and .com from the string.
        break
    else:
        myweb.append(mywebsite)
