How can I remove newline characters from a string in Python?

In Python, you can remove newline characters from a string using different methods. Here's a detailed explanation of a few commonly used approaches:
Using the replace() method:
Thereplace() method is a built-in string method that can be used to replace occurrences of a substring with another substring. You can usemy_string.replace('\n', '') to remove newline characters ('\n') from the string.
In this example,my_string.replace('\n', '') removes newline characters from the string"Hello\nWorld!". The resulting string, with newline characters removed, is assigned to the variableresult and printed.
Using the strip() method:
Thestrip() method is a built-in string method that can remove specified characters from the beginning and end of a string. By passing'\n' as an argument tostrip(), you can remove newline characters from the string.
In this example,my_string.strip('\n') removes newline characters from the string"Hello\nWorld!". The resulting string, with newline characters removed from both ends, is assigned to the variableresult and displayed.
Using regular expressions:
If you want to remove all types of newline characters, including\n,\r, or\r\n, you can use regular expressions (re module) to replace them with an empty string.

import re
my_string = "Hello\nWorld!"
result = re.sub(r'[\r\n]+', '', my_string)
print(result)
In this example,re.sub(r'[\r\n]+', '', my_string) uses a regular expression pattern[\r\n]+ to match one or more newline characters. There.sub() function replaces the matched pattern with an empty string, effectively removing all newline characters. The resulting string is
