A problem with opening a file -- again

Sun Nov 29 16:36:09 EST 2020

Hi guys,
I tried to solve the problem once again. I have inserted some print
statements the check the variables.
The actual code (naplo.py) is copy-pasted here:
----
class Naplo:
 def __init__(self, pNeve, pMeret, pMode = 'a'):
 self.logNev = pNeve
 self.meret = pMeret
 self.startMode = pMode
 self.mode = 'a'
 self.sor = 0
 self.puffer = []
 self.start = True
 def __del__(self):
 print(' .. sor = %d'%self.sor)
 print(' .. startMode = %s'%self.startMode)
 print(' .. mode = %s'%self.mode)
 print(' .. logName = %s'%self.logNev)
 print(self.puffer)
 if self.sor != 0:
 if self.start:
 trc = open(self.logNev,self.startMode)
 else:
 trc = open(self.logNev,self.mode)
 for idx in xrange(self.meret):
 trc.write(self.puffer[idx])
 trc.close()
 def Kiir(self, txt):
 msg = '%s\n'%txt
 self.puffer.append(msg)
 self.sor += 1
 print(' .. sor = %d'%self.sor)
 print(' .. startMode = %s'%self.startMode)
 print(' .. mode = %s'%self.mode)
 print(' .. logName = %s'%self.logNev)
 print(self.puffer)
 print('.. ' + self.logNev)
 if self.sor == self.meret:
 if self.start:
 trc = open(self.logNev,self.startMode)
 else:
 trc = open(self.logNev,self.mode)
 for idx in xrange(self.meret):
 trc.write(self.puffer[idx])
 trc.close()
 self.start = False
 self.puffer = []
 self.sor = 0
lf = Naplo('nap1.log', 6)
lf.Kiir('Ez az elso.')
