python 2.7 - Conditional statement not redirecting like it should -


i'm new python , working on stript gets user input redirect part of program. i'm using conditional statement either go or exit. when press key continue exits. please help

def infomenu(): = '''     1 = volume information     2 = volume status     3 = display peer status     4 = ctdb status     5 = ctdb ip     6 = display ctdb config file  ''' print a = raw_input('enter option: ')  if == '1':         option = raw_input('please enter name of vol: ')         subprocess.call(['gluster vol ', option, 'info'], shell=false)  elif == '2':    option = raw_input('please enter name of vol: ')    subprocess.call(['gluster vol ', option, 'status'], shell=false)  elif == '3':    subprocess.call(['lvdisplay'], shell=false)    answer = raw_input('press 0 go or exit (default[0]): ')     if answer == '0':        printoptions()    else:        exit()  elif == '4':     option = raw_input('please enter name of vol')     subprocess.call(['gluster vol ', option, 'info'], shell=false)  elif == '5':     option = raw_input('please enter name of vol')     subprocess.call(['gluster vol ', option, 'info'], shell=false) else:     exit()

i'm talking condition statement 3 when press 0 suppose go beginning menu , else should exit. doing wrong.

tracing code:

  1. function infomenu() run
  2. if user enters "3" (return)
  3. your subprocess.call run
  4. then user asked new input

after code , description don't seem match, because if user enters "0", calling other function (which isn't included) called "printoptions()"

a super simple fix (that break if ever return) re-call infomenu in place of printoptions call, suspect better off better off rewriting.

if trying described (using style) do:

def infomenu():     def thing1():         pass #do_somethings()      def thing2():         #do_someotherthings()         user_input = raw_input('press 0 go or exit (default[0]): ')         if (len(user_input)==0) or (user_input == '0'):             return         else:             exit()     a="""     1 = thing1     2 = thing2     """     print     user_input = raw_input('enter option')     if user_input == '1':         thing1()     if user_input == '2':         thing2()  while 1:     infomenu()
