python - IndentationError: expected an indented block 10 -


यहाँ कोड है 

  import RPi.GPIO GPIO आयात समय GPIO.setmode ( GPIO.BCM) GPIO.setup (2, GPIO.IN) सच है, तो: यदि GPIO.input (2) == गलत: प्रिंट ("मार्शल्लो एक अच्छा इनपुट बनाता है") time.sleep (0.5) फ़ाइल "marshmallow.py" , लाइन 11 प्रिंट ("मार्शमॉलो एक अच्छा इनपुट बनाता है") ^ इंडेंटेशन एरर: अपेक्षित एक इंडेंट ब्लॉक   
 मुझे एक पुस्तक से यह कोड मिला है और मुझे यकीन नहीं है कि क्या गलत है ... < / 
 
 
  यदि  ब्लॉक (या उस बात के लिए कोई ब्लॉक) में कोड होना चाहिए ब्लॉक खोलने वाले कथन से आगे बढ़ें इस संदर्भ में, इसका मतलब है कि आपका कोड इस तरह दिखना चाहिए:  
  जबकि सही: GPIO.input (2) == गलत: प्रिंट ("मार्शमॉल एक अच्छा इनपुट करता है") time.sleep (0.5)   
 या शायद यह पसंद है:  
  जबकि सही: अगर GPIO.input (2) == गलत: प्रिंट ("मार्शमॉलो एक अच्छा बनाता है इनपुट ") time.sleep (0.5)   
 आपने जो कोड पोस्ट किया है, यह पूरी तरह से स्पष्ट नहीं है कि आप इनमें से कौन सा दो चाहते हैं (हालांकि यह संभवतः पूर्व है - आप संभवत: बनना चाहते हैं प्रत्येक पाश चलने पर सो रहा है)।  
 यह भी ध्यान रखें कि पायथन कोड में, यह पसंद किया जाता है कि प्रत्येक स्तर के इंडैेंडेशन में 4 रिक्त स्थान शामिल हैं, न कि 2 - तो  आदर्श , यह कोड इस प्रकार दिखाई देगा:    < / html>

java - Instances of classes -

Does a non-static method make an example of that class in which it is declared? Why does this code work? import java.awt. *; Public Class Main Frame {PUBLIC MAN () {// SUPER KEYWORDS Do not Need a Class Shelter? Super ("My Frames"); Supersatsis (200,100); } Public static zero main (string [] args) {new main (); }} If a non-static method creates an example of a class, the next code should work ... import.java.applet . *; Public class extends the main applet (public zero print) (System.out.println ("Hi");} Public Zero Init () {this.print ();}} A non-static method can only be accessed In the context of an example Pre-existing .

python - how we can use ajax() in views.py in django? -

I have a little code here. Could you please tell me what this code really does? please. Here in the AJAX call: $ .ajax ({url: "{% url} upload_document '%}", type: "POST", data : {Csrfmiddletoken: document.getElementsByName ('csrfmiddletoken') [0] Price, Title: document.getElementById ('title'). Value, // document: document: document.getElementById ('document'),}, datatype: "Jason", success: function (feedback) {if (feedback == "true") {// success} other {// attachment errors}}}); How AJAX works in the Django and how we can see the AJAX request. Here is the idea of ​​my thoughts def upload_document (requested): Print request. POTT print request FILES if request.is_ajax (): If request.method == 'POST': form = UploadForm (request.POST, request.FILES, user = request.user) if form.is_valid (): Form.save () return HTTPPCS (SimpleJason Dumps ('True'), Mime Type = 'App / Jason') Other:...

javascript - Is there any way to add a new parameter to a function programmatically? -

Since I can set the number of expectations by calling a function its function.length Property, do I have to programmatically create the right number of parameters to include in that function at runtime? Example: var xyz = function (a, b) {}; Var BCD = function (A, B, C, D, E, F) {}; // vararg example var doc = document, func_length = xyz.length; Doc.xyz = (function () {returns function (A, B, C, D, E) works for one / but other is not}}}. Call (doctor); / * With `only two parameters ', like' Return function (A, B)`, if this function is used for `xyz` (although in this case 5 works fine), and return function ( If the function is used for 'BCD' (which does not work with only five parameters) with A, B, C, D, E, F) `6 / / Xyz.apply (blank, arguments) Think about ... but which logic ..? : // Returning function (A, B, C, D, E) does not support work with more than five parameters, which will be mostly class - hence my question / I also know very well That I use an obj...
