在Python MULTILINE模式下仅匹配字符串的开头

Question

Python's re module says this:

'^'

(Caret.) Matches the start of the string, and in MULTILINE mode also matches immediately after each newline.

I want to use MULTILINE but I want to require a match at the beginning of the string (not just the beginning of a line). Is there a way to do this?

Answer 1

Just use the \\A anchor that matches the start of string unambiguously.

Check the Regular Expression Syntax :

\\A
Matches only at the start of the string.
