你好，有人可以，描述一下这段代码的算法。类似于pythonTutor.com，但网站无法使用外部文件。
j = 0
self.pole = []
while True:
newLine = t.readline().strip()
if newLine == '':
break
for i in range(len(newLine)):
if newLine[i] == 'v':
self.vajce = Vajce(i*40+20, j*40+20) #this is class witch i am calling
newLine = riadok.replace('v','.')
if newLine[i] == 'z':
self.dvere[j,i] = Dvere(i*40, j*40) # another class
self.pole.append(list(newLine))
j += 1

t = open(meno_suboru)
# open a file to read in
j = 0
# initialise line counter
self.pole = []
# create list to hold things
self.dvere = {}
# create dictionary to hold other things
while True:
# loop until condition met
riadok = t.readline().strip()
# get the next line from t and strip the newline character, whitespace etc
if newLine == '':
# if we've reached a blank line
break
# we're done
for i in range(len(riadok)):
# count through the characters in the new line
if riadok[i] == 'v':
# if current character is a 'v'
self.vajce = Vajce(i*40+20, j*40+20)
# create a new Vjace object and set to self.vajce
raidok = riadok.replace('v','.')
# replace all 'v's in the line with '.'s to prevent further matches
# so we only ever have one self.vjace
if newLine[i] == 'z':
# if current character is a 'z'
self.dvere[j,i] = Dvere(i*40, j*40)
# same as before, but self.dvere is a dictionary so we
# keep any previous Dvere objects too - dictionary key
# is a tuple (j, i)
self.pole.append(list(riadok))
# turn the line into a list of characters and add to the self.pole list
j += 1
# increment the line counter
请注意，这可以更好地构建：
with open(meno_suboru) as t: not 'open()' and 'close()'
for j, riadok in enumerate(t): # not 'while True:'
# use index j and line riadok
...
for i, char in riadok: # not 'for i in range(len(riadok)):'
# use index i and character char
...
