我是python的新手。我在一个文件telnet.py中使用telnet连接，并在另一个文件debug.py中登录。但是在成功建立telnet连接之后，当我查看日志文件时，我看到在日志文件的每一行中都添加了^M。有人可以指导我摆脱日志文件中的^M吗？预先感谢。
文件名：telnet.py
tn = telnetlib.Telnet(HOST)
cmdout = tn.read_until(b"ogin")
Logging(str(cmdout))
tn.write(user.encode('ascii') + b"\r")
文件名：debug.py
LOG_FILE = 'testing.log'
logging.basicConfig(filename=LOG_FILE, level=logging.DEBUG, format='%
(asctime)s: %(levelname)s: %(message)s')
log = logging.getLogger()
def Logging(msg):
log.debug(msg)
日志文件日志如下：
switch login
2019-03-22 11:33:37,623: DEBUG: : Password:
2019-03-22 11:33:37,927: DEBUG: ^M

收到消息后，只需修剪任何\r\n并重新添加\n。
def Logging(msg):
msg = msg.rstrip('\r\n') + '\n'
log.debug(msg)
如果消息可能是多行，请拆分并重新组合：
def Logging(msg):
lines = [line.rstrip('\r') for line in msg.split('\n')]
msg = '\n'.join(lines)
log.debug(msg)

您可以使用my-app/

node_modules/
package.json
public/
index.html
favicon.ico
src/
|components/
|Clien/
|Home.js
|Home.css
|Header.js

查找并用模式替换匹配的字符串。 SELECT
A.Id_partner ,A.Id_account ,A.Date,A.actual_review ,B.review_recommended
FROM table1 AS A
LEFT JOIN Review AS B
ON A.Id_account = B.Id_account
AND A.Id_partner = B.Id_partner
为您做得很好。

您可以读取日志文件，并在python中使用replace方法：
def remove_caret_m_from_the_old_log_file_and_create_a_new_log_file_without_it():
# Read the old log file.
the_file = open("your_log_file.txt", "r")
initial_content = the_file.read()
# Remove '^M'.
desired_content = initial_content.replace('^M', '')
# Write the new content into a new log file.
the_new_file = open('your_new_log_file.txt', 'x')
the_new_file.write(desired_content)
