loops - How to restart a program in python? -


im student, , started learning python month back, right now, have learnt basics. teacher had given me qeustion this, , problem is, dont know how rerun program, suppose, after finding area of particular shape, want loop printing first statement. there way of doing without rerunning program using "f5" key? thankyou.

 print "1. triangle"  print "2. circle"  print "3. rectangle"   shape= input("please select serial number =")   if shape==1:      a=input("base =")      b=input("height =")      area=0.5*a*b      print area  if shape==2:      a=input("radius =")      area=3.14*a*a      print area  if shape==3:      a=input("width")      b=input("length")      area=a*b      print area

if want restart, use simple while loop.

while true:     # lovely code

then put validation @ end:

    again = raw_input("play again? ")     if again.startswith('n') or again.startswith('n'):         break     else:          continue
