Regex matches all but not empty

Question

The string must be validated with a regular expression,

I tried this:

[A-Za-z0-9~`!#$%^&*()_+-]+ //thinking of all the characters

Any alternative solution would be helpful

Try this to match a string containing more than just spaces

/.*\S.*/

It means

/= delimiter
.*= zero or nothing more than a new line
\S= everything except spaces (new line, tab, space)

so that you get a match nothing but a new line + something not whitespace + nothing but a new line

, /.+/, 1 .

: [^()]

python re.match():

  >>> re.match( r"[^()]", '' )
  >>> re.match( r"[^()]", ' ' )
  <_sre.SRE_Match object at 0x100486168>

, NOT BLANK:

^(\s|\S)*(\S)+(\s|\S)*$

Empty lines are those that contain only empty characters (tabs, spaces, etc.).
