Python - How to check if string is a HEX Color Code -


i need help!

im kinda new whats regarding python , "hex".

i have site people can enter own hex-color messages.

so have built in except "ishexcolor" check..

i realy dont know how can sure user gave valid hex-color-code.

currently im checking if len 6 digits, nothing more.

if not len(color) == 6: return error("hex-color" must contain 6 characters")

can might me? , should work python 2.5!

you use regular expression:

^#(?:[0-9a-fa-f]{3}){1,2}$

for using regular expression in python https://docs.python.org/2/library/re.html

import re str = '#ffffff' # hex  match = re.search(r'^#(?:[0-9a-fa-f]{3}){1,2}$', str)  if match:                         print 'hex valid'  else:   print 'hex not valid'

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
