It can be preceded and followed by anything, any character or whitespace sequence (including new lines): (.|\s)*. … Read more
if(str.find_first_not_of(‘ ‘) != std::string::npos) { // There’s a non-space. }
There is no particular symbol for whitespace.

Don’t use print …, (with a trailing comma) if you don’t want spaces. Use string concatenation or formatting. Concatenation: print ‘Value is “‘ + str(value) + ‘”‘ Formatting: print ‘Value is “{}”‘.format(value) The latter is far more flexible, see the str.format() method documentation and the Formatting String Syntax section. You’ll also come across the older … Read more
