Your problem is that you are adding a preliminary 1 to 1/1 which gives 2. Try this: def count(n): sum = 0 #Intializing the return variable for i in range(1, n+1): sum+=1.0/i #Adding to the return variable return sum This works as such: >>> def count(n): … sum = 0 … for i in range(1, … Read more
So, if I’m reading your post correctly, you are trying to perform a bitwise comparison against your value ({DataTableCable.ColumnChange}) in the Crystal Reports code. Looking around online, I can’t seem to see anything that indicates that crystal can perform that kind of comparison. One alternative is to perform that calculation in your .Net code, and … Read more
With your example equation, Rody’s answer provides an analytic solution. In general, however, given an equation f(x,y)=0 it may not be possible to find an analytic solution. In that case I suggest: Define a target x, y area and generate random samples within it. Compute z = abs(f(x,y)) at the sample points. Sort the values … Read more
In the second argument it is actually ++i!=0, The loop is interpreted as for(++i;++i!=0;++i) If you start with a positive i or 0, it will be an infinite loop and will invoke undefined behavior when i reaches INT_MAX. If i was -Ve initially the loop may stop at a defined run. EDIT: As you changed … Read more
Your question is very unclear and I may be way off, but here is my attempt to your question. $link = array(‘S1, Ep1’, ‘S1, Ep2’, ‘S1, Ep3’, ‘S1, Ep10’); $results = preg_replace_callback(‘~^S(\d+)\D+(\d+)$~m’, function($m) { $which = strlen($m[2]) > 1 ? ’00’ : ‘000’; return $m[1] . $which . $m[2]; }, array_values($link)); print_r($results); Output Array ( … Read more
The following returns a CGRect holding the size of your device’s screen in points. [[UIScreen mainScreen] bounds]; Note that the following would return the size of your screen without the status bar. Try to think of this as the frame rectangle for your application’s window. [[UIScreen mainScreen] applicationFrame]; 2 solved How can I detect a … Read more
You need regular expressions for this: import re s=”abc xyz.xyz(1, 2, 3) pqr” re.sub(r'[a-z]{3}\.{[a-z]{3}\([^)]*\)’, ‘NULL’, s) Explanation: [a-z]{3} stands for 3 small letters (lower case) \. escapes the dot, as it is special character [a-z]{3} again 3 small letters \( escapes the left parenthesis [^)]* any character but right parenthesis, 0 or more time \) … Read more
File file = new File(“test.txt”); String word = “abc,catch,profile”; Scanner scanner = null; try { scanner = new Scanner(file); } catch (FileNotFoundException e) { System.out.println(“Error ” + e); } // now read the file line by line while (scanner.hasNextLine()) { String line = scanner.nextLine(); StringTokenizer st = new StringTokenizer(word, “,”); while (st.hasMoreTokens()) { if (line.contains(st.nextToken())) … Read more
The code you have: sum = 0; while (sum < a + b) { sum += a; } will only add a to the sum until the sum becomes a + b. You would need to use a * b in the while loop in that case but, as stated, you’re not allowed to. Since … Read more
Its a old version of mssql so does not support above solutions but when i tried like this it works EXEC sys.sp_rename ‘fg.TABLE NAME.OLD_COLUMN_NAME’,’NEW_COLUMN_NAME’,’COLUMN’; anyway thanks for your efforts solved How to rename a column in SQL Server 2005 [duplicate]
To call a the same function as a button press on a keypress you have to bind keypress to you GUI. Example try: # for Python2 from Tkinter import * except ImportError: # for Python3 from tkinter import * class GUI(Frame): # Create and return a packed frame. def frame(self, side): w = Frame(self) w.pack(side=side, … Read more
I don’t know what data base are you using. You can search for “Bulk Insert” for your data base, it allows you to insert complete file in one step. If you need to create an instruction like this: INSERT CodesTable VALUES (91111), (91112), … (91999) You could open/copy&past the file in query editor. Make a … Read more
You are assigning to print instead of using it as a function. Remove the =, call the function instead: print(“Hi {}, You go to {} don’t you”. format (x,y)) Demo: >>> x = input(‘Enter your Name : ‘) Enter your Name : Martijn Pieters >>> y = input(‘Enter your School : ‘) Enter your School … Read more
you are using arithmetic operations on strings. that for sure makes no sense create a float from the textfield input if ([_label3.text floatValue] >= 20.0) {_label4.text = @”0″;} aslo you have to change the 1st and 2nd else branch, a the last one will never be called, as if it is true, the fist one … Read more
