Method in Python\n
and \t
from a string.Remove
\n
From the String in Python Using the str.strip[]
Method\n
from the string using the str.strip[]
method, we need to pass \n
and \t
to the method, and it will return the copy of the original string after removing \n
and \t
from the string.str.strip[]
method only removes the substrings from the string’s start and end position.string = "\tHello, how are you\n"
print["Old String:"]
print["'" + string + "'"]
string = string.strip['\n']
string = string.strip['\t']
print["New String:"]
print["'" + string + "'"]
Old String:
' Hello, how are you?
'
New String:
'Hello, how are you?'
Remove
\n
From String Using str.replace[]
Method in Python\n
and \t
from a string is to use the str.replace[]
method. We should keep in mind that the str.replace[]
method will replace the given string from the whole thing, not just from the string’s start or end. If you only need to remove something from the start and end only, you should use the str.strip[]
method.str.replace[]
method two
arguments as input, first is the character or string you want to be replaced, and second is the character or string you want to replace with. In the below example, since we just wanted to remove \n
and \t
, we have passed the empty string as the second argument.
Example code:
string = "Hello, \nhow are you\t?\n"
print["Old String:"]
print["'" + string + "'"]
string = string.replace['\n',""]
string = string.replace['\t',""]
print["New String:"]
print["'" + string + "'"]
Output:
Old String:
'Hello,
how are you ?
'
New String:
'Hello, how are you?'
Remove \n
From String Using regex
Method in Python
To
remove \n
from the string, we can use the re.sub[]
method. The below code example demonstrates how to remove \n
using the re.sub[]
method. \n
is the new line’s regular express pattern, and it will be replaced with the empty string - ""
.
import re
string = "Hello, \nhow are you\n?"
print["Old String:"]
print["'" + string + "'"]
new_string = re.sub[r'\n', '', string]
print["New String:"]
print["'" + new_string + "'"]
Output:
Old String:
'Hello,
how are you
?'
New String:
'Hello, how are you?'

Function to Remove a Newline Character From the String in Python
Like other popular programming
languages, Python also has a newline character indicated by \n
. It is essentially used to trace the culmination of a line and the emergence of a new line in a string.
Newline characters can also be used in f-strings. Moreover, according to the Python documentation, print statements add a newline character at the end of a string by default.
This tutorial will discuss different methods to remove a newline character from a string in Python.
Use the strip[]
Function to Remove a Newline Character From the String in Python
The strip[]
function is used to remove both trailing and leading newlines from the string that it is being operated on. It also removes the whitespaces on both sides of the string.
The following code uses the strip[]
function to remove a newline character from a string in Python.
str1 = "\n Starbucks has the best coffee \n"
newstr = str1.strip[]
print[newstr]
Output:
Starbucks has the best coffee
The
rstrip[]
function can be used instead of the strip function if there is only the need to remove trailing newline characters. The leading newline characters are not affected by this function and remain as they are.
The following code uses the rstrip[]
function to remove a newline character from a string in Python.
str1 = "\n Starbucks has the best coffee \n"
newstr = str1.rstrip[]
print[newstr]
Output:
Starbucks has the best coffee
Use the replace[]
Function to Remove a Newline
Character From the String in Python
Also known as the brute force method, It uses the for
loop and replace[]
function. We look for the newline character \n
as a string inside a string, and manually replace that from each string with the help of the for
loop.
We use a List of strings and implement this method on it. Lists are one of the four built-in datatypes provided in Python and can be utilized to stock multiple items in a single variable.
The following code uses the replace[]
function to remove a newline character from a string in Python.
list1 = ["Starbucks\n", "has the \nbest", "coffee\n\n "]
rez = []
for x in list1:
rez.append[x.replace["\n", ""]]
print["New list : " + str[rez]]
Output:
New list : ['Starbucks', 'has the best', 'coffee ']
Use the re.sub[]
Function to Remove a Newline Character From the String in Python
The re
module needs to import to the python code to use the re.sub[]
function
The re
module is a built-in module in Python, which deals with regular expression. It helps in performing the task of searching for a pattern in a given particular string.
The re.sub[]
function is essentially used to take a substring and replace its occurrence in the string with another substring.
The following code uses the re.sub[]
function to remove a newline character from a string in Python.
#import the regex library
import re
list1 = ["Starbucks\n", "has the \nbest", "coffee\n\n "]
rez = []
for sub in list1:
rez.append[sub.replace["\n", ""]]
print["New List : " + str[rez]]
Output:
New List : ['Starbucks', 'has the best', 'coffee ']
