Split String on Second Occurrence of Character in Python

You can use split(), join(), and RegEx functions to split a string on a second occurrence in Python.

The following examples explain how you can split the string based on a second occurrence of a character in Python.

Using split() and join() functions

This example explains how to split a string on a second occurrence of a character using the split() and join() functions.

Suppose you have the following example string

# example string
x = "ABC_DE_XY_Z"

Split the x string with a second occurrence of _ character.

# split string on second occurrence of `_` character
"_".join(x.split("_", 2)[:2])

# output
'ABC_DE'

In the above example, we first split the string with _ character into two parts and then again joined the first split using the _ character.

Using split() from RegEx

This example explains how to split a string on a second occurrence of a character using the split() function from re package.

# example String
x = "ABC,DE,XY,Z"

Split the x string with a second occurrence of , character.

# import package
import re

# split string on second occurrence of `,` character
",".join(re.split(",", x, maxsplit=2):2])

In the above example, we used RegEx (re package) to split the string with , character into two parts and then again joined the first split using the , character.
