Question

while loop == 6:
if EVENTCOUNT >= 4:
                _, username, para, value = event.split(" ", 3)
                try:
                        self.dbcur.execute('select ? from users where name = ?', [para, username])
                        if rrf is None:
                                print notex
                        else:
                                print str(username)+" has been altered: "+str(para)+" => "+str(value)+"."
                        while loop == 2:
                                again = raw_input("Is that all? (Y/N)")
                        while True:
                                if again == "Y":
                                # edit another parameter
                                        loop=4
                            elif again == "N":
                                    print "Thanks! Bye! \nAll credits of this program go to Trey."
                                    #end program
                                    break
                    else:
                            print "Sorry! That wasn't Y or N."
                            loop == 2

我收到错误：“IndentationError：预计会出现缩进块”，如果EVENTCOUNT＆gt; = 4下面有错误：

使用IDE，它通常具有缩进工具，用于自动将混合制表符和空格转换为所有制表符或空格。这是你的代码，每个缩进有4个空格。

while loop == 6:
    if EVENTCOUNT >= 4:
        _, username, para, value = event.split(" ", 3)
        try:
            self.dbcur.execute('select ? from users where name = ?', [para, username])
            if rrf is None:
                print notex
            else:
                print str(username)+" has been altered: "+str(para)+" => "+str(value)+"."
            while loop == 2:
                again = raw_input("Is that all? (Y/N)")
            while True:
                if again == "Y":
                # edit another parameter
                    loop=4
                elif again == "N":
                    print "Thanks! Bye! \nAll credits of this program go to Trey."
                    #end program
                    break
            else:
                print "Sorry! That wasn't Y or N."
                loop == 2
        except Exception,err:
            print "error"

您必须对文件中的所有块使用一致的缩进 - 我（和PEP8）强烈建议使用四个空格。

在单个文件中混合制表符和空格很糟糕，因为制表符根据开发人员的环境具有可变的感知宽度。混合单个文件中的空格数可能会使解释器混淆。
