仅当两个连续的行以 python 开头并正常写入其余文本时才合并

Question

Input

02000|42163,54|
03100|4|6070,00
03110|||6070,00|00|00|
00000|31751150201912001|01072000600074639|
02000|288465,76|
03100|11|9060,00
03110|||1299,00|00|
03110||||7761,00|00|
03100|29|14031,21
03110|||14031,21|00|
00000|31757328201912001|01072000601021393|

法典

prev = ''
with open('out.txt') as f:
for line in f:
if prev.startswith('03110') and line.startswith('03110'):
print(prev.strip()+ '|03100|XX|PARCELA|' + line)
prev = line

嗨，我有这段代码，可以搜索两个连续的行是否以 03110 开头并打印这些行，但我想转换代码，以便它打印或写入.txt其余行

输出应该是这样的

02000|42163,54|
03100|4|6070,00
03110|||6070,00|00|00|
00000|31751150201912001|01072000600074639|
02000|288465,76|
03100|11|9060,00
03110|||1299,00|00|3100|XX|PARCELA|03110||||7761,00|00|
03100|29|14031,21
03110|||14031,21|00|
00000|31757328201912001|01072000601021393|

我知道我只合并了这两行，因为这是 print(( 的命令

03110|||1299,00|00|3100|XX|PARCELA|03110||||7761,00|00|

但是我不知道要输出所需的输出，任何人都可以帮助我编写代码吗？

# I assume the input is in a text file:
with open('myFile.txt', 'r') as my_file:
splited_line = [line.rstrip().split('|') for line in my_file] # this will split every line as a separate list
new_list = []
for i in range(len(splited_line)):
try:
if splited_line[i][0] == '03110' and splited_line[i-1][0] == '03110': # if the current line and the previous line start with 03110
first = '|'.join(splited_line[i-1])
second = '|'.join(splited_line[i])
newLine = first + "|03100|XX|PARCELA|"+ second
new_list.append(newLine)
elif splited_line[i][0] == '03110' and splited_line[i+1][0] == '03110': # to escape duplicating in the list
pass
else:
line = '|'.join(splited_line[i])
new_list.append(line)
except IndexError:
pass
#  To write the new_list to text files
with open('new_file' , 'a') as f:
for item in new_list:
print(item)
f.write(item + 'n')
