What is the output of this ML code? -

- 

  मजेदार वर्ग (x: int) = x * x; मानचित्र (~, मानचित्र (वर्ग, मानचित्र (~, [1, 2, 3])));

क्या यह सिर्फ तीन नंबरों का वर्ग होगा (1, 4, 9)? मैंने इसे न्यू जर्सी के एसएमएल पर चलाने की कोशिश की लेकिन इस त्रुटि को देखते हुए ... 

  - मज़ेदार वर्ग (x: int) = x * x; Val square = fn: int - & gt; अंतर मानचित्र (~, मानचित्र (वर्ग, नक्शा (~, [1,2,3]))); StdIn: 3.11-3.35 त्रुटि: ऑपरेटर और परिचालन सहमत नहीं है [टाइॉन बेमेल] ऑपरेटर डोमेन: 'Z - & gt; 'वाई प्रचार्य: (एक्स -> एक्स) अभिव्यक्ति में * इंट सूची: नक्शा (~, 1 :: 2 :: और लेफ्टिनेंट; एक्सपी & gt; :: & lt; exp & gt;) stdIn: 3.4-3.36 त्रुटि: ऑपरेटर और ऑपरेंड सहमत न हो [टाइकॉन बेमेल] ऑपरेटर डोमेन: 'Z - & gt; 'वाई ऑपरेंड: (इंट-> इंट) * _ अभिव्यक्ति में: मानचित्र (स्क्वायर, मैप (~, & lt; exp & gt; :: & lt; exp & gt;)) stdIn: 3.1-3.36 त्रुटि: ऑपरेटर और परिचालन सहमत नहीं है [टाइकॉन बेमेल] ऑपरेटर डोमेन: 'Z - & gt; 'वाई प्रचालक: एक्सप्रेशंस में: (' एक्स - & gt; 'एक्स) * _: मानचित्र (~, मानचित्र (स्क्वायर, मैप & lt; exp & gt;)) -

< Div class = "post-text" itemprop = "text">

जैसा कि आपने खुद को पाया, केवल एक चीज जो यह कोड प्रिंट करेगी वह एक त्रुटि संदेश है। इसका कारण यह है कि नक्शा एक क्युर्ड फंक्शन है और ट्यूपल के रूप में इसके तर्कों को नहीं लेता है।

इसे ठीक करने के लिए, आपको map कॉल करने की आवश्यकता है > एक क्युरीड फ़ंक्शन के रूप में (अर्थात मैप एफ एक्सएस बजाय map (f, xs) )।

I am working on the terminal on a shell script after this tutorial SQLAlchemy tutorial.

uislider - In a MATLAB GUI, how does one implement a continuously varying slider from a GUIDE created .m file? -

-
I am trying to create a GUI with a plot and a slider. The slider should be described as continuously and output. I have a problem with this explanation that the uicontrol object is programmatically created, on the contrary, I want to know that in the last three instances, to complete the same thing done according to the program What can be added to a GUI file that is created. The code is down, and I have marked the (wrong) code that is provided by some of the above examples. Thanks a lot for any help! This slider function sets P1_slider_Callback (hObject, eventdata, handle) (handle, dragon, 'string', num2str (get (hObject, 'value'), 3)) PlottheData_Callback ( HOBject, EventData, Handle)% "PlotHeadata" is a button that creates the data slider based on the value of P1_slider%, and I think that here "p1_slider_CreateFcn" (hObject, eventdata, handle) needs to be assembled (HOBJECT, 'BackgroundRoller'), (0, 'Default UITTACKBACK MANDROLLE...

python - Django Custom Admin Block For center of admin -

-
So I'm overriding change_form.html to add some features to my admin page. Everything is working fine, I am currently using the "after_field_sets" block, but I want to put content between this field in my field_sets, not after that. I set the field above and below the new set, but I can not understand which block is used to put them in the middle of field sets. There is a list of all blocks text "> After reading the code referenced by the link you posted I reached the conclusion that the block you are looking for does not exist in it called content There is a block but more than just that "main content" but this is not the end of the world, you still have to make the template IR order to "make some space" for your content. Remember Padit can. And very important, keep in mind that you can css and js edit files as well.
