Python convert multi line into single line formatted string

[karthidec]

Hi, Pls help me on the below issue. I have tried a lot, but not getting correct format.

I have a python flask application where I am getting inputs from a User and POST to JIRA application to create ticket.

One of my field is description and it is a multi-line field.

Expected Input: [in description field, which is multi-line]
testinput1
testinput2
testinput3

Expected output format: [Need in this format for JIRA post rest api process]
\\ntestinput1\\ntestinput1\\ntestinput1\\n

I tried so far,

b=request.form['description'] # I gave multi-line inputs in this field thru front end UI screen
a='''{b}'''.format(b=b)
print(a)
out=a.replace("\n", "\\n")
print(out)

What is the behavior you are observing and what is your expectation?

What is the behavior you are observing and what is your expectation?

Currently, I am getting an output like below

#input - multi line input thru front end UI screen
t12
t14

#output
\12
t14

Expectation:

#to support jira rest api format, I need formatted string like below
\\nt12\\nt14\\n

---

I just tried like below and got expected output (able to post successfully in JIRA to create ticket)
Pls let me know, if any other efficient way to handling this string format.

#get input from UI screen and place in multi line quote string
input_desc='''{}'''.format(request.form['description'])
#convert each line into array list
format_desc=input_desc.splitlines()

description=""
for i in format_desc:
  description=description+i+'\\n'

Output:

testline1\ntestline2\ntestline3\n
