What's the regular expression that matches a square bracket?
(10 answers)
Closed 3 years ago.
Trying to search bbcode-style tags with regular expression:
For example, I needed [user=1]John Dow[/user] with regular: [[user=[0-9]+].*?[/user]]
But couldn't receive needed result.
Remove the outer pair of brackets and escape the literal brackets (unlike the range-of-characters brackets)
let pattern = "\\[user=[0-9]+\\].*?\\[/user\\]"

I'm trying to remove any row that contains a "?" in a particular column.
I have this line:
df[~df.C.str.contains("?")]
which doesn't work. I get the following error:
error: nothing to repeat at position 0
However the following does work
df[~df.C.str.contains("abc")]
Does anyone know what it is about ? that stops it running?
.str.contains() expects a regular expression by default; ? is treated as a metacharacter, and using it alone will raise re.error.* Pass regex=False to search for a literal "?" character:
df[~df.C.str.contains("?", regex=False)]
* See re.compile("?")

Is it possible to get a copyright symbol in C# Console application?

How do i output special characters to the console in visual basic. because simply putting console.writeline("Copyright symbol") outputs a C instead of the symbol. how can i fix this.
You can use the ChrW() function with the Unicode decimal value of the symbol you want to print, for the Copyright symbol it is 169.
console.writeline(ChrW(169))
You can find the Unicode decimal values for other symbols on this website.
The real copyright symbol is a unicode character. Use \u00A9 instead of C to print it out correctly.

WHERE Variable = 'Lowe's';
But string is ending at Lowe because it recognizes the 's as end of String.

Although escaping ' with '' works, in case you are running this command from any application you should take a look at databinding and using SqlParameters - spares you a lot of headache, improves performance and security.

Anyone have any idea?
This following will do what you want without using regex (and is more readable than a regex solution):
Dim s As String = "some sentence that i want to capitalise"
Debug.WriteLine(Globalization.CultureInfo.CurrentCulture.TextInfo.ToTitleCase(s))
Output:
Some Sentence That I Want To Capitalise
And you can also do this (from the Microsoft.VisualBasic Namespace):
Debug.WriteLine(StrConv(s, VbStrConv.ProperCase))
You can do that using regular expressions. There are a useful class named Regex that will help you a lot. Please follow this link for more information.
