In Python, you can split strings without removing the delimiter character using the
split() method of strings with a slight modification. The
split() method by default removes the delimiter character from the resulting list of substrings. However, you can use a technique called “capturing groups” to include the delimiter character in the resulting list of substrings.
Here’s an example:
import re my_string = "Hello,world;how are you today?" delimiter_pattern = r"([,;])" split_strings = re.split(delimiter_pattern, my_string) result = [s for s in split_strings if s] print(result)
In this example, we first import the
re module, which provides regular expression functionality in Python.
We then define the string we want to split,
my_string, and the delimiter pattern we want to use to split the string. In this case, we use the regular expression pattern
([,;]), which matches either a comma or a semicolon, and captures the delimiter character in a group.
We then use the
re.split() method to split the string using the delimiter pattern, and assign the result to
To include the delimiter character in the resulting list of substrings, we use a list comprehension to filter out empty strings and keep only non-empty strings in the
The output of this example code would be:
['Hello', ',', 'world', ';', 'how are you today?']
Note that the delimiter characters are included in the resulting list of substrings. If you want to remove the empty strings from the resulting list of substrings, you can use a list comprehension with a condition to filter them out, as shown in the example above.
