prompt

默认情况下ftp里面的交互式提示是开启的，平常如果下载多个文件时，这种提示很让人烦，如果是在shell脚本里面要从ftp服务器上一次mget多个文件，写个交互式很麻烦，最好是把这个交互式提示关掉。 进入ftp命令后，prompt会将交互式提示的配置置反，如果原先交互式提示是开着的，则使用prompt之后就关闭，如果原先是关闭的，则使用prompt后就打开。当然也可以直接加参数prompt on或者prompt off。 转载于:https://www.cnblogs.com/Richardzhu/p/3154291.html 来源： https://blog.csdn.net/weixin_30268071/article/details/99105213

1.构造和析造 魔法方法就是被双下划线包围的方法 __init__() 方法 __init__ 方法默认没有参数，返回值为none。类实例化对象需有明确的初始化步骤要重写函数 >>> class Rectangle: def __init__(self,x,y): self.x = x self.y = y def getPeri(self): return (self.x+self.y)*2 def getArea(self): return self.x * self.y >>> rect = Rectangle(3,4) >>> rect.getPeri() 14 >>> rect.getArea() 12 >>> #init返回值一定是None >>> class A: def __init__(self): return "A" >>> a = A() Traceback (most recent call last): File "", line 1, in a = A() TypeError: __init__() should return None, not 'str' __new__() 方法 __new__() 方法在实例化对象时返回一个实例对象，参数是cls，是第一个被调用的方法 >>> class CapStr(str): def __new__(cls

Scenario: An interactive CLI Python program, that is in need for a password. That means also, there's no GUI solution possible. In bash I could get a password read in without re-prompting it on screen via read -s Is there something similar for Python? I.e., password = raw_input('Password: ', dont_print_statement_back_to_screen) Alternative: Replace the typed characters with '*' before sending them back to screen (aka browser' style). >>> import getpass >>> pw = getpass.getpass() Yes, getpass : "Prompt the user for a password without echoing." Edit: I had not played with this module myself yet,

Is it possible to have a bash script automatically handle prompts that would normally be presented to the user with default actions? Currently I am using a bash script to call an in-house tool that will display prompts to the user (prompting for Y/N) to complete actions, however the script I'm writing needs to be completely "hands-off", so I need a way to send Y|N to the prompt to allow the program to continue execution. Is this possible? unwind This is not "auto-completion", this is automation. One common tool for these things is called Expect . You might also get away with just piping input

I have a requirement to implement an "Unsaved Changes" prompt in an ASP .Net application. If a user modifies controls on a web form, and attempts to navigate away before saving, a prompt should appear warning them that they have unsaved changes, and give them the option to cancel and stay on the current page. The prompt should not display if the user hasn't touched any of the controls. Ideally I'd like to implement this in JavaScript, but before I go down the path of rolling my own code, are there any existing frameworks or recommended design patterns for achieving this? Ideally I'd like
