问题 This question already has answers here : In Python interpreter, return without “ ' ” (2 answers) Closed last year . In the Python interactive prompt, if you return a string, it will be displayed with quotes around it. But if you just print the string, it will not be shown with quotes. Why? >>> a='world' >>> a 'world' >>> print(a) world 回答1: Simply put: The quotes allow python to treat whatever is inside of them as a 'string literal'; that way, if we wanted to write a string like 'print([0, 1,

问题 I just learned switch statements. I was practicing it by building something. When i set the value of variable to a number it works but when i asks the user for a number it always outputs the default statement .

But in sh… $ dash -c 'printf "What is your password? "; read

As of today {N} do not expose the underlaying native view for dialogs so it's not possible to override natively. You will have to build the complete custom dialog yourself to achieve what you are

问题 ansible 2.1.2.0 I have a situation here for which I'm trying to check with you all to see if the solution is even possible with Ansible vars_prompt feature and when conditional. Ansible has this feature called: vars_prompt and I want to club this with the when conditional ( when: ... which we generally use in tasks at task or playbook level actions) PS: My question is different than this post : Ansible to Conditionally Prompt for a Variable? i.e. my vars: variables are not dependent upon any
