Removing hyphen (-) between two words creates empty elements in a list

Question

I am trying to get rid of hyphens in words in a list through the below code


listA=['End-to-End Encryption']

listmain= '-'.join(listA).split('-')

The output I get is

['End', '', '', 'to', '', '', 'End', 'Encryption']

How do I get rid of unnecessary blank elements created

Ideal output required

['End', 'to', 'End', 'Encryption']

How to achieve this.

I don't think so list allows blank elements, and your code works for me there is no empty elements. — Juhil Somaiya, Dec 03 '19 at 07:11
I have run your code and my output is different than yours. What is your python version? — Farhood ET, Dec 03 '19 at 07:15
@I'L'I This solution worked. str_list = filter(None, str_list). Thanks — venkatttaknev, Dec 03 '19 at 07:23

Split it by multiple separators. By regex.

listA = ['End-to-End Encryption']
listmain = re.split(r'\s|-', listA[0])

This should do the job and is dynamic for more than 1 sent in listA

listmain = [val.replace("-"," ").split() for val in listA]

Eg:

listA = ["End-to-End Encryption", "End-to-End Decryption"]
listmain = [val.replace("-"," ").split() for val in listA]

O/P:

[["End", "to" ,"End", "Encryption"],["End","to","End","Decryption"]]

The following code works flawlessly:

listA=['End-to-End Encryption']
for el in listA:
    str2 = el.split('-')
    print(str2)

The Output of this code is:

['End', 'to', 'End Encryption']
