python - Prevent input() from being anything but alphabet characters -


i attempting make program sake of self-knowledge. want ask user name is, , want user able use letters alphabet answer, or strings. not want them able answer numbers, symbols, etc.

def cc():   name = (input("""hello, happens first name?           > """))   if type(name) str:       print("you have entered name correctly.")   elif type(name) int:       print("your name cannot integer. try again.")       cc()  cc()

you can enforce requirement using str.isalpha. documentation:

return true if characters in string alphabetic , there @ least 1 character, false otherwise. alphabetic characters characters defined in unicode character database “letter”, i.e., general category property being 1 of “lm”, “lt”, “lu”, “ll”, or “lo”. note different “alphabetic” property defined in unicode standard.

here example program:

while true:     name = input('enter name using alphabetic characters: ')     if name.isalpha():         break

demo:

enter name using alphabetic characters:  bo2 enter name using alphabetic characters:  bo^&*( enter name using alphabetic characters:  bob

note method not work people hyphenated names such "anne-marie".

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 ...
