Question

我有一个代码，它读取文件并从该文件中随机选择一行，并通过DM作为不和谐机器人发送。但是，我希望它读取txt文件的某个部分，该部分以哪个字符开头和结尾。例如：你好，

这是我正在使用的代码，它读取随机行并通过DM发送它：

emailFile = open("C:/Users/jacob/Downloads/Spotify_premiums.txt", "r")
emails = []
for email in emailFile:
    emails.append(email)

@bot.command(pass_context = True)
@commands.cooldown(1, 30, commands.BucketType.user)
@commands.has_any_role("| Premium |")
async def spotifypremium(ctx):
    msg = emails
    await bot.send_message(ctx.message.author, random.choice(msg))
    await bot.send_message(ctx.message.channel, "Alt Has Been Seen To Your DMs")
    await bot.purge_from(ctx.message.channel, limit=2)
    await bot.send_message(ctx.message.author, "Please Wait 30 Seconds Before Using This Command Again. If you do not wait the full time then you won't be sent an alt.")

这是我的修订版：

    emailFile = open("C:/Users/jacob/Downloads/Uplay_Formatted.txt", "r", 
    encoding="utf16").read()
    parse = False
    email = []
    for com in emailFile.split('\n'):
        if com.startswith(',Credentials'):
            parse = True
        elif com.startswith(',Credentials'):
            parse = False
        if parse:
            email.append(com)


    @bot.command(pass_context = True)
    @commands.cooldown(1, 30, commands.BucketType.user)
    @commands.has_any_role("| Premium |")
    async def spotifypremium(ctx):
            msg = email
            await bot.send_message(ctx.message.author, random.choice(msg))
            await bot.send_message(ctx.message.channel, "Alt Has Been Seen 
    To Your DMs")
            await bot.purge_from(ctx.message.channel, limit=2)
            await bot.send_message(ctx.message.author, "Please Wait 30 
    Seconds Before Using This Command Again. If you do not wait the full 
    time then you won't be sent an alt.")

Answer 1

您还可以使用startswith（）和endswith（）示例here

例如，在你的情况下;这将是这样的：

emailFile = open("C:/Users/jacob/Downloads/Spotify_premiums.txt", "r")
read_emails = emailFile.read()
emails = [com for com in read_emails.split() if com.startswith(',') and com.endswith(',')]

根据您的要求在开始和结束之间显示内容。试试这个：

emailFile = open("C:/Users/jacob/Downloads/Spotify_premiums.txt", "r", encoding="utf8").read()
parse = False
for com in emailFile.split('\n'):
    if com.startswith(',Credentials'):
        parse = True
    elif com.startswith(',Credentials'):
        parse = False
    if parse:
        #do stuff

如果您只是想从文本文件中获取电子邮件地址。

import re

emailFile = open("C:/Users/jacob/Downloads/Spotify_premiums.txt", "r", encoding="utf8").read()
email = []
for com in emailFile.split():
    if re.match(r'[\w\.-]+@[\w\.-]+',  com):
        email.append(com)

Answer 2

尝试使用正则表达式https://docs.python.org/2/library/re.html

您可以匹配以单词＆＃39;嗨＆＃39;开头的行。 re.match('^Hi', line)

^表示该行的开头，还有一些其他可能有用的特殊字符。

如何根据特定字符
