python-如何在for循环中更改为另一行文件

我有一个ifs和elses(不写)长函数,而whatnot包含一个for循环,用于在文件的每一行中查找：

def check(low,high):
    with open('users.txt', 'r+') as followed:
        ts = time.time()
        sttime = datetime.fromtimestamp(ts).strftime('%Y%m%d_%H:%M:%S - ')
        done_checking = open('done_checking.txt', "a")
        done = 0
        skippers = 0
        max_tries = 15
        for line in followed:
            if skippers==30:
                print "MAKE THE FOR LOOP GO BACK TO LINE 1 OF FILE"
            else:

                print "Does some other stuff"

                if done==max_tries:
                    sleep(randint(850,1150))
                    done = 0

                elif:
                    print: "SCRIPT DOES SOME STUFF!"

                else:
                    skippers += 1
                    print: "SCRIPT HAS SKIPPED A USER"                  

有没有办法说

“使循环回到文件的第1行”

我可以将for循环重置为要检查的文件的第一行(users.txt)吗？

(显然,它的打印内容是：“ SCRIPT DOESS SOME STUFF！”,我在时间戳上发生了很多混乱的事情……)

解决方法:

“MAKE THE FOR LOOP GO BACK TO LINE 1 OF FILE”

是的,您需要调用seek函数返回所需的行.

fileobject.seek(0)

这将返回到该特定文件的第1行.
