Does python have a “use strict;” and “use warnings;” like in perl?

由 旧时模样 提交于 2019-12-02 21:01:55
I am learning perl and python... at the same time, not my by design but it has to be done. Question: In a perl script I use(see below) at the head of my txt. #!/usr/bin/env perl use strict; use warnings; Is there something I should be doing on routine for my python scripts? LeoNerd To provide an answer that perhaps avoids a little of the commentary noise here, I'll try another one. The two pragmata in your original question really expand to: use strict "vars"; use strict "refs"; use strict "subs"; use warnings; To answer each in turn: The effect of use strict "vars" is to cause a compile-time

reset() - “Strict Standards: Only variables should be passed by reference” [duplicate]

问题 This question already has answers here : Strict Standards: Only variables should be passed by reference (6 answers) Closed 5 years ago . I am currently moving a website over for a client. Their old host must be using an old version of PHP from what I can gather. The site is currently working on their current host. I am working to move this to a new host for them and I am getting the following error: PHP Strict Standards: Only variables should be passed by reference in /home/parcelt2/core

Can 'use strict' warn instead of error

由 ε祈祈猫儿з 提交于 2019-12-01 19:03:01
When using use strict perl will generate a runtime error on unsafe constructs. Now I am wondering if it is possible to have it only print a warning instead of causing a runtime error ? Or is use warnings (or -w) warning about the same issues ? I'm gonna take a stab at guessing the real motivation here. Feel free to tell me if I guessed wrong. I suspect your trying to tackle a large, older code base and would like to enable strictures but you were hoping first to get a sense of where the errors will be (and how many there are) without breaking functionality. Unfortunately, since use strict

Using a dynamically generated variable name in Perl's strict mode [duplicate]

由 99封情书 提交于 2019-12-01 17:52:53
This question already has an answer here: How can I use a variable as a variable name in Perl? 3 answers Basically, I would like to grab the contents of a variable named in a dynamically generated string, but all efforts to accomplish this in strict mode have failed. There are several posts about similar problems, but none seem to have solutions that have worked for me. This is what I want to do: # Fields: $q1 = "ex. data 1"; $q2 = "ex. data 2"; $q3 = "ex. data 3"; $q4 = "ex. data 4"; $q5 = "ex. data 5"; # retrieve the desired field name. q1, q2, q3, q4, or q5. $field_name = fetch_the_desired

Using Dumper not triggering a failure

由 混江龙づ霸主 提交于 2019-12-01 00:22:37
when running code like this: use strict; print Dumper "something"; nothing is printed out and no error occurs during compile and runtime. Why does this happen? Why doesn't strict prevent this code from running? Why is there no error at runtime, even though Dumper is unknown? I know it produces a warning when those are explicitly enabled, but I'm interested why is this code considered "correct" in any way. One of the valid syntaxes for print is print FILEHANDLE LIST In your program Perl is treating Dumper as a filehandle glob. Running this code with warnings enabled will tell you: print() on

'caller' and 'arguments' are restricted function properties and cannot be accessed in this context

由 白昼怎懂夜的黑 提交于 2019-11-30 17:08:58
I am trying to create a simple debugging function that simply shows the caller of a function, like this: function xe() { console.log(xe.caller().name) } With this I would just be able to add xe() to a function and it will log the calls to the function– just a short, simple addition to help with debugging. Debugging sugar, so to speak. Unfortunately I get the error from the subject-line: TypeError: 'caller' and 'arguments' are restricted function properties and cannot be accessed in this context. I am using Babel/ES6, which injects "use strict" at the top of every module. This may be the cause,

Replicating arguments.callee in strict mode

由 廉价感情. 提交于 2019-11-30 14:58:51
问题 I'm working in strict mode for the first time and, what-d'ya-know, it's also the first time in ages being able to use a non strict mode property would be useful. My question here outlines the exact problem I'm having, but the solution I've worked out could be adapted to something a lot more scaleable if I still had access to arguments.callee. Without naming the function is there any way in strict mode that I can get a reference to the function whose scope I'm currently within? 回答1: Without
