Template strings provide simpler string substitutions as described in PEP 292. A primary use case for template strings is for internationalization (i18n) since in that context, the simpler syntax and functionality makes it easier to translate than other built-in string formatting facilities in Python.The solution is to use Python’s raw string notation for regular expression patterns; backslashes are not handled in any special way in a string literal prefixed with 'r'. So r" " is a two-character string containing '\' and 'n', while " " is a one-character string containing a newline. Usually patterns will be expressed in Python code using ...We would like to show you a description here but the site won’t allow us.Here, we will cover 4 different methods to Remove Newline From String in Python: Using the Python replace () function.
