Bypassing ZeroDivisionError

How can I bypass the ZeroDivisionError and allow the program to continue whilst noting the 0 value?

for line in data:
  split=line.split()
  ptot=0
  ntot=0
  for pchar in "HKR":
    pchartotal=split[1].count(pchar)
    #print pchartotal
    ptot+=pchartotal
  for nchar in "DE":
    nchartotal=split[1].count(nchar)
    #print nchartotal
    ntot+=nchartotal
  print float(ptot)/float(ntot)

Or you could just test and substitute the value when detecting a zero divisor;

print ('NA' if not ntot else float(ptot)/float(ntot))

Try:

try:
    print (1/0)
except ZeroDivisionError:
    print ("Yo that's divide by zero")

print ("Done cya")

You can use try{..} except{..} block

try:
    print float(ptot)/float(ntot)
except ZeroDivisionError:
   print 'divide by zero'

you can use try-except :

for line in data:
  split=line.split()
  ptot=0
  ntot=0
  for pchar in "HKR":
    pchartotal=split[1].count(pchar)
    #print pchartotal
    ptot+=pchartotal
  for nchar in "DE":
    nchartotal=split[1].count(nchar)
    #print nchartotal
    ntot+=nchartotal
  try:
    print float(ptot)/float(ntot)
  except ZeroDivisionError :
    print "ZeroDivisionError: integer division or modulo by zero"

change this:

print float(ptot)/float(ntot)

to

try:
    print float(ptot)/float(ntot)
except ZeroDivisionError as err:
    print err
