Question

我想以编程方式将@RestControllerAdvice添加到django settings.py文件中，如下所示：

之前：

后：

//MARK: calculate
    func calculate()
    {
        outPutLabel.hidden=true

        if(birthDayTxt.text?.characters.count>0)
        {
             outPutLabel.hidden=false

            let calendar = NSCalendar.currentCalendar()


            let dateFormatter = NSDateFormatter()
            dateFormatter.dateStyle = .LongStyle

            //birthday
            let Fromdate = dateFormatter.dateFromString(birthDayTxt.text!)

            let Components1 = calendar.components([NSCalendarUnit.Day, NSCalendarUnit.Month, NSCalendarUnit.Year], fromDate:Fromdate!)

            self.FromDateValue = calendar.dateFromComponents(Components1)!

            //today
            let Components2 = calendar.components([NSCalendarUnit.Day, NSCalendarUnit.Month, NSCalendarUnit.Year], fromDate:NSDate())

            self.ToValueDate = calendar.dateFromComponents(Components2)!
            print(ToValueDate)



            let diffDateComponents = NSCalendar.currentCalendar().components([NSCalendarUnit.Year, NSCalendarUnit.Month, NSCalendarUnit.Day, NSCalendarUnit.Hour, NSCalendarUnit.Minute], fromDate: FromDateValue!, toDate: ToValueDate!, options: NSCalendarOptions.init(rawValue: 0))

            let str="\(diffDateComponents.year) years, \(diffDateComponents.month) months, \(diffDateComponents.day) days"
            outPutLabel.text=str
            animateLabel(outPutLabel)
        }

    }

我想到的是以下步骤：

在文件中找到'someapp'字符串
找到... ... INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', ] ...字符串以指示解析字符串的结尾。
获取... ... INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'someapp', ] ...中的所有项目以避免冲突
将^INSTALLED_APPS = [添加到]

这看起来像一个简单的问题，但我仍然想知道如何用最佳实践来做到这一点。

虽然这是关于python脚本的，但是也欢迎使用GNU工具的bash脚本，如sed，awk，grep。

如何使用python或gnu工具解析并在文件中插入一行
