Python accessing global variables using globals() -


नीचे दिए गए उदाहरण में देखें .. 

  var1 = 10 var2 = "string" var3 = सच डिक = {} def func1 (): ... ... def मुख्य (): varN = globals ()। ["Var1"] शब्दकोश = ग्लोबल्स ()। ["डिक"]। Var2 ('कुछ अन्य स्ट्रिंग ')

इसे कैसे पढ़ें? ग्लोबल्स ()? यह कैसे प्रयोग किया जाता है और व्याख्या की जाती है?

कृपया मदद करें धन्यवाद।

ग्लोबल्स () एक शब्दकोश देता है।

< प्री> प्रिंट प्रकार (ग्लोबल्स ()) # & lt; टाइप 'डिक्ट' & gt;

इसलिए, वैश्विक चर का उपयोग करने के लिए सबस्क्रिप्ट नोटेशन पर्याप्त है। 

  प्रिंट ग्लोबल्स () ["var1"] ग्लोबल्स () ["dic"] [Var2] = 'कुछ अन्य स्ट्रिंग' प्रिंट डिक # {'स्ट्रिंग': 'कुछ अन्य स्ट्रिंग'}

Python, converting png to gif using ImageMagick -

I am using Python 2.7.6, I had a problem converting some PNG files into GIF (an animation To create) os.system ("Convert-dated 1-Digiage background + page" + str (output_dir) + "/*.png -loop 0" + str (output_dir) + "/ Animation GIF") This was the error on which I have Parametre non welde - 1 Enough to go Without error, this is only an estimate, but ... If there is an empty space or quote in output_dir or other special characters, to avoid or quote you Nothing is doing, so your command line will look something like this: Convert - Day 1-digest background + page ~ / My image / *.
