How do I create a space around special characters in python?-CodePudding

This is what I want the code to do:

string = "1 1 1"

#insert code here

output:
>>>1   1   1

Basically I'm trying to create a " " around the special characters. (In this case it's the plus signs)

CodePudding user response：

For the above string you can try this as there is only one special character

print('   '.join(S.split(" ")))

print(S.replace(" ","   "))

If you have multiple of them then try something like

result = ""
for char in string:
    if char in special_chars:
        result  = " " char " "
    else:
        result  = char
print(result)

CodePudding user response：

You can split them first, and then re-join them


special_char= ' '
string= "1 1 1".split(special_char)
string= f' {special_char} '.join(string)

CodePudding user response：

You can try something like this

import re
string = "1 1 1"
print(re.escape(string).replace("\\"," "))

Here the output that i got

1  1  1

You'll need to better define special characters. But anyway the solution is to .split() the string and then .join() it like that:

my_string = "1 1 1"    
delimiter = ' '
my_string = f' {delimiter} '.join(my_string.split(delimiter))

EDIT
Based on your comment here is example for multiple delimiters:

my_string = "1 1-1"
delimiters = [' ', '-']
for delimiter in delimiters
    my_string = f' {delimiter} '.join(my_string.split(delimiter))
