Split a string by a plus sign (+) character

Use

strsplit("(1)+(2)", "\\+")

or

strsplit("(1)+(2)", "+", fixed = TRUE)

The idea of using strsplit("(1)+(2)", "+") doesn't work since unless specified otherwise, the split argument is a regular expression, and the + character is special in regex. Other characters that also need extra care are

• ?
• *
• .
• ^
• $
• \
• |
• { }
• [ ]
• ( )

Below Worked for me:

import re

re.split('\\+', 'ABC+CDE')

Output:

['ABC', 'CDE']
