python - making a dictionary from two lists using indices -

-

मेरे पास दो सूचियां हैं: 

  alist = [11,12,13,11, 15] blist = ['ए', 'ए', 'बी', 'ए', 'बी']   
 मैं एक शब्दकोश बनाना चाहता हूं जहां फॉल्स में चीजें कुंजियां और आइटम हैं Alist में सूचियों के साथ दो सूचियों में सूचकांकों के लिए मान हैं:  
 परिणाम होना चाहिए:  
  {'ए': [11, 12, 11], ' बी ': [13, 15]}   
 मैंने इसे करने की कोशिश की है:  
  dictNames = {} एक्सरेन्ज में (लेन (अलविदा)): Blist में पत्र के लिए: यदि पत्र नहीं dictNames: dictNames [letter] = [] अन्य: dictNames [letter] .append (alist [i])   
 जो परिणाम देता है:   
 यह पहले से मौजूद अक्षर को डिक्शनरी में संलग्न करने के बजाय क्यों नहीं जोड़ता है शब्दकोश में पहले से ही?   
 
 
 पहले, आप दोनों सूचियों पर लूप। अलविदा में हर आइटम के लिए, यह blist के माध्यम से loops तो आंतरिक पाश 25 बार चलाता है इसके बजाय, आप इसे 5 गुना चलाना चाहते हैं, इसलिए आप केवल एक लूप चाहते हैं।  
 दूसरा, यदि आप अभी तक मौजूद नहीं हैं, तो आप सही ढंग से सूची को इनिशियलाइज़ कर सकते हैं, लेकिन उस स्थिति में नंबर सूची में जोड़ा नहीं गया है । नंबर हमेशा सूची में जोड़ दिया जाना चाहिए, भले ही यह एक नई सूची है।  
 मैंने ये कोड दो चीजों को ध्यान में रखने के लिए अपना कोड बदल दिया है, और यह थोड़ा बेहतर काम करता है:  
  के लिए मैं एक्सरेन्ज (लेन (आलियास्ट)) में: letter = blist [i] यदि अक्षर नहीं में तदनुसार नाम: dictNames [letter] = [] dictNames [letter] .append (alist [i])   
 आउटपुट:  
  {'ए': [11, 12, 11], 'बी': [13, 15]}

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

So, I ended up making a Sudoku Solver, but I want to improve it. To do this, I need to reach betterJTextField to documentListener . I am using a documentListener to read from my betterJTextFields in real-time, I have the problem that insertUpdate (DocumentEvent e) .
