Sure it’s a regular expression’s newbie question, I saw it in a program but I can’t understand the part of the two backslashes, Does “\\” have a special meaning like \r or \t?
[a-zA-Z]+\\.?
Thank you
The backslash (\) is the escape character in your regular expression pattern which is why \r and \t work, they are regular characters preceded with the escape character to denote a special character you can’t just type on your keyboard. To tell the pattern matcher that it should look for an actual backslash, which is what your pattern is doing, you have to escape it thus creating \\.
