# Python | Splitting operators in a string

| |

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’]
