Method # 1: Using re.split()
This task can be accomplished using the split function provided by the Python regex library that can split string under certain conditions, and in this case — all numbers and operators.

# Python3 code to demonstrate how it works
# Line splitting operators
# Using re.split ()

import re

# initialization string

test_str = "15 + 22 * 3-4 / 2 "

# print original line

print ( "The original string is:" + str (test_str))

# Using re.split ()
# Line splitting operators

res = re.split (r ’(D)’ , test_str)

# print result

print ( " The list after performing split functionality: " + str (res))

Output:

The original string is: 15 + 22 * 3-4 / 2
The list after performing split functionality: [’15’, ’+’, ’22’, ’*’, ’3’, ’-’, ’4’, ’/’, ’2’]

Method # 2: Using re.findall ()
This Python regex library function can also do the same task as the above function. It can also support decimal numbers as additional functionality.

# Python3 code to demonstrate how it works
# Line splitting operators
# Using re.findall ()

import re

# initializing string

test_str = "15 + 22.6 * 3-4 / 2 "

# print original line

print ( "The original string is:" + str < / code> (test_str))

   
  # Using re.findall ()  
  # Line splitting operators  
   res   =   re.findall (r   ’[0-9.] + | [^ 0-9.] + ’ , test_str) 
    
  # print result  
   print   (  "The list after performing split functionality:"   +   str   (res))

Output:

The original string is: 15 + 22.6 * 3-4 / 2
The list after performing split functionality: [’15’, ’+’, ’22 .6 ’,’ * ’ , ’3’, ’-’, ’4’, ’/’, ’2’]
