addition

I have two integers in my program; let's call them " a " and " b ". I would like to add them together and get another integer as a result. These are regular Python int objects. I'm wondering; how do I add them together with Twisted? Is there a special performAsynchronousAddition function somewhere? Do I need a Deferred ? What about the reactor? Is the reactor involved? OK, to be clear. Twisted doesn't do anything about cpu bound tasks and for good reason. there's no way to make a compute bound job go any quicker by reordering subtasks; the only thing you could possibly do is add more compute

I have a matrix like this A=[ 1 2; 2 3; 3 4; 4 5; 5 6; 6 8; 7 9; 8 5; 9 4] Now I want to add a second column the condition is that if limit=0, and interval=3 and limit=limit+interval, or in other words, I have to sum column 2 when values of column 1, ranges like 0 to 3, 3 to 6, 6 to 9, and 9 to 12, and i want sum of corresponding values of column 2. my solution will be like that range- sum 0 to 3 9 3 to 6 19 6 to 9 18 like that I have a matrix of around 7000x2. In place of range just serial no may also be given. This is just an example. This is a job for ACCUMARRAY . First, you construct an

I'm a novice Assembly x86 Learner, and i want to add two numbers (5+5) and print the result on the screen. here is my code: global _start section .text _start: mov eax, 5 mov ebx, 5 add eax, ebx push eax mov eax, 4 ; call the write syscall mov ebx, 1 ; STDOUT pop ecx ; Result mov edx, 0x1 int 0x80 ; Exit mov eax, 0x1 xor ebx, ebx int 0x80 Correct me please Another approach to convert an unsigned integer to a string and write it: section .text global _start _start: mov eax, 1234567890 mov ebx, 5 add eax, ebx ; Convert EAX to ASCII and store it onto the stack sub esp, 16 ; reserve space on the

I converted my csv file to text file and I want to add the numbers inside the text file. When I run my code get an error. Assuming the error code I want to write logic that would bypass my strings and just add the numeric values. `import csv csv_file = 'Annual Budget.csv' txt_file = 'annual_budget.txt' with open(txt_file, 'w') as my_output_file: with open(csv_file, 'r') as my_input_file: reader = csv.reader(my_input_file) for row in reader: my_output_file.write(" ".join(row)+'\n') data = [] with open(r'annual_budget.txt') as f: for line in f: fields = line.split() rowdata = map(float, fields)

How to add elements individually within the tuple? For example, i need (2, 4) from (0,1) + (2,3) , I've been doing it as such but is there a more pythonic / less verbose way to do the same? >>> x = (0,1) >>> y = (2,3) >>> x + y (0, 1, 2, 3) >>> tuple(i+j for i,j in zip(x,y)) (2, 4) James Mills You can use zip and sum here: Example: >>> x = (0, 1) >>> y = (2, 3) >>> tuple(map(sum, zip(x, y))) (2, 4) zip lets us combine elements of two iterables or lists in pairs. sum lets us sum the pairs map lets us apply the sum function per pair. finally we convert the resulting list ( or iterable in Python
