Else是無效語法

Question 1

我寫了一些代碼，將下載一個網頁，然后搜索某個字符串，我知道這是一個低效的方式來做它，但這是我選擇的方式，無論如何，代碼總是出現一個無效的語法為其他人。歡迎任何幫助！代碼：

import requests
from discord import Webhook, RequestsWebhookAdapter

#download website and turns into a .txt file
while true:
    print('Beginning file download with requests')
    url = str(input("Enter Profile ID:"))
    r = requests.get(url)
    with open('/Users/Computer/Desktop/Notification/[profile.txt', 'wb') as f:
     f.write(r.content)

# Retrieve HTTP meta-data
print(r.status_code)
print(r.headers['content-type'])
print(r.encoding)
#opens text file and searches for a certain keyword
with open('/Users/Computer/Desktop/Notification/[profile.txt') as f:
    if 'avatar-status online profile-avatar-status icon-online' in f.read():#if it finds the keyword it sleeps and then retries
        time.sleep(20)
    continue
#if it doesnt find the keyword (meaning they are offline) it sends you a message through discord webhook
    else:
    webhook = Webhook.from_url("YOUR WEBHOOK HERE!", adapter=RequestsWebhookAdapter())
    webhook.send("Found string")

Question 2

你需要在True中大寫T
您的continue在while之外，因為它沒有縮進。
您的continue在if之外，因為它沒有縮進，這就斷開了else與if的連接
你的else正文沒有縮進

while True: # Capitalize
    print('Beginning file download with requests')
    url = str(input("Enter Profile ID:"))
    r = requests.get(url)
    with open('/Users/Computer/Desktop/Notification/[profile.txt', 'wb') as f:
        f.write(r.content)

    # Indent everything below this
    print(r.status_code)
    print(r.headers['content-type'])
    print(r.encoding)
    #opens text file and searches for a certain keyword
    with open('/Users/Computer/Desktop/Notification/[profile.txt') as f:
        if 'avatar-status online profile-avatar-status icon-online' in f.read():
            time.sleep(20)
            continue # indent this to align with the sleep
        else:
            webhook = Webhook.from_url("YOUR WEBHOOK HERE!", adapter=RequestsWebhookAdapter()) # indent this to be in the else
            webhook.send("Found string") # indent this too

進一步細化：

你根本不需要那個額外的文件，搜索r.content一個字節字符串
input()返回str()，所以不需要轉換它
在if/else之后什么都沒有，所以你不需要continue

while True:
    print('Beginning file download with requests')
    url = input("Enter Profile ID:")
    r = requests.get(url)
    print(r.status_code)
    print(r.headers['content-type'])
    print(r.encoding)
    if b'avatar-status online profile-avatar-status icon-online' in r.content:
        time.sleep(20)
    else:
        webhook = Webhook.from_url("YOUR WEBHOOK HERE!", adapter=RequestsWebhookAdapter())
        webhook.send("Found string")
