Solving systems of equations in two variables - Python -


i start learn python , learned variables, input , basic math.

i been asked write mathematical exercise has parameters:

ax+by=c, dx+ey=f

a, b, c, d,e, f - user input , program result , write answear x, y

i did:

number1 = float(input('insert number1: '))  number2 = float(input('insert number2: '))  number3 = float(input('insert number3: '))  number4 = float(input('insert number4: '))  number5 = float(input('insert number:5 '))  number6 = float(input('insert number6: '))

i don't how write equation 2 variables

x=number1+2.5*number2-number3 #(it should looked ax+by=c)  y=number5+2.5*number6-number4

ax+by=c , dx+ey=f ==> x=(-by+ey-f+c)(a-d)

i don't know why can't write variable inside print:

print('the value of x, y is') print((x))

well, must think in way solve equation 2 variables using programming language, it's not straightforward if you're not familiar programming.

think steps have take solve manually first , try implement using python, i'll try guiding:

1- find number multiply 1 of equations can "remove" 1 of variables.

2- sum both of equations (forget variables now, work coefficients)

3- after summing both equations , storing "new_coefficient" values , assuming removed x should have like: ((e*step_1_number)+b)*y = f*step_1_number + c

4- previous step you'll able find y value, after it's pretty easy find x value.

i managed using python don't think it's going useful if post code, try work out yourself, luck!

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
