I get a java.util.regex.PatternSyntaxException when splitting a string in PySpark

What happened

When I did the following

from pyspark.sql import functions as F

split_col = F.split(df["hoge"], "?")

I got the following error

java.util.regex.PatternSyntaxException: Dangling meta character '?' near index 0

Coping

Apparently, ? Is regarded as a regular expression symbol.

To avoid it, replace ? With \\?.

split_col = F.split(df["hoge"], "\\?")

reference

I referred to the following page. Thank you very much.

Workaround for error'Dangling meta character'?'
