python added all line /n

Question

According to the condition of the script, it should not add to each line \n, but when it is executed, all the text is in spaces and parted

import sys

import fileinput

nameuser = "users1"
psuser = "pass1"

file_name = '/usr/local/etc/3proxy.cfg'
for line in fileinput.FileInput(file_name,inplace=1):
    if 'auth strong' in line:
        line = line.replace(line, line+'########################################################################## '+ nameuser +' ##########################################################################'+'\r' + 'users '+ nameuser +':CL:'+ psuser +'\r'+ 'allow login,'+ nameuser +'\r''flush')
        print (line)

unformatted file:

daemon

nserver 11111
nserver 22222
nscache 65536

timeouts 1 5 30 60 180 1800 15 60
log /var/log/3proxy/log D
logformat "- +_L%t.%. %N.%p %E %U %C:%c %R:%r %O %I %h %T"
logformat "L%t.%. %N.%p %E %U %C:%c %R:%r %Q:%q %O %I %h %T %n "

rotate 360
#external 0.0.0.0
#internal 0.0.0.0

auth strong

deny *

maxconn 254

setgid 65534
setuid 65534

Each script run adds "\n" to all lines. file format after script

daemon

nserver 11111

nserver 22222

nscache 65536

timeouts 1 5 30 60 180 1800 15 60
log /var/log/3proxy/log D

logformat "- +_L%t.%. %N.%p %E %U %C:%c %R:%r %O %I %h %T"

logformat "L%t.%. %N.%p %E %U %C:%c %R:%r %Q:%q %O %I %h %T %n "

rotate 360

#external 0.0.0.0

#internal 0.0.0.0

auth strong

deny *

maxconn 254

setgid 6553

setuid 65534

I added different fragments "\r", "\n", "\r\n" , but nothing happened

Please make your code a [mre] that people who aren't you can run _without changes_ to see the problem and test proposed fixes. If your problem is with file input, we shouldn't need a SQL database or a `/usr/local/etc` file to test if the issue is fixed. — Charles Duffy, Jan 31 '23 at 19:54
(similarly, showing both actual and expected output _as part of the question_ will make it clearer to readers) — Charles Duffy, Jan 31 '23 at 19:56
Not sure how `line = line.strip()` followed by `line = line.replace()` doesn't cause an error. `line` becomes a list which shouldn't have a `replace` method. — Michael Cao, Jan 31 '23 at 20:18
@MichaelCao Are you mixing up `strip` and `split`? Because `strip` just removes whitespaces. — cadolphs, Jan 31 '23 at 20:24
By default, `print` adds a newline. See here for what to do about that: https://stackoverflow.com/questions/493386/how-to-print-without-a-newline-or-space — cadolphs, Jan 31 '23 at 20:49
@cadolphs print(line, sep=""), not working and outputs the same as in the example and adds \n — Андрей, Jan 31 '23 at 20:57
