我想在文件中找到特定的行，在该行的末尾添加一个字符串，然后更新文件，但是更新后的文件在行之间有多余的空白行。
def Reading_Logging(PacketName, PacketTot, PacketNum):
try:
with open("C:\\Users\\Shakib\\Desktop\\test.txt", "r+") as f:
content = f.read().splitlines()
#print(names_list)
for i, l in enumerate(content):
tnow = datetime.datetime.now()
linesplit = l.split(',')
if linesplit[0] == PacketName and linesplit[1] == PacketTot and linesplit[2] == PacketNum:
content[i] = content[i].replace(content[i], content[i] + ',' + str(tnow))
with open("C:\\Users\\Shakib\\Desktop\\newtest.txt", "w") as f:
f.write('\n'.join(content))
我希望以下输出没有空行，但这是我的真实输出：
