I have
12.hello.mp3 21.true.mp3 35.good.mp3 . . . so on as file names in listed in a text file.
I need to replace only those dots(.) infront of numbers with a space.(e.g. 12.hello.mp3 => 12 hello.mp3). If I have regex as "[0-9].", it replaces number also. Please help me.

To use RegEx, the first argument of replace will be replaced with regex syntax, for example /regex/ . This syntax serves as a pattern where any parts of the string that match it will be replaced with the new substring. The string 3foobar4 matches the regex /\d. *\d/ , so it is replaced.
Put a capture group around the part that you want to preserve, and then include a reference to that capture group within your replacement text. @Amber: I infer from your answer that unlike str. replace(), we can't use variables a) in raw strings; or b) as an argument to re. sub; or c) both.
For example, the replacement pattern $1 indicates that the matched substring is to be replaced by the first captured group.
Replace
^(\d+)\.(.*mp3)$ with
\1 \2 Also, in recent versions of notepad++, it will also accept the following, which is also accepted by other IDEs/editors (eg. JetBrains products like Intellij IDEA):
$1 $2 This assumes that the notepad++ regex matching engine supports groups. What the regex basically means is: match the digits in front of the first dot as group 1 and everything after it as group 2 (but only if it ends with mp3)

I tested with vscode. You must use groups with parentheses (group of regex)
1 a text 2 another text 3 yet more text (\d)\s $1- 1-a text 2-another text 3-yet more text If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
