itertools.filterfalse() is used with the lambda functionlambda x:x==''as the filter criteria. The lambda function checks if each elementxin the list is equal to an empty string.filterfalse()returns an iterator containing the
To remove multiple characters from a string using regular expressions in Python, you can use there.sub()function from theremodule. This function allows you to replace patterns (in this case, characters) with an empty string, effectively removing them from the string. In the below example, there...
We can also use the regular expression to remove and replace a newline character from a string in python. There.sub()function is used to find and replace characters in a string. We will use this function to replace the newline character with an empty character in a given string in python...
