So, this is a good opportunity to use purrr::map. You are half way there by applying code to one dataframe.

You can take the code that you have written above and put it into a function.

Because you can't have braces in that context. If you look at cppreference on list initialization, you see that the case inside a ternary operator isn't defined. So it can't be parsed correctly and you get the error you have.

You'd have to use something like this :

What are the differences between GNU grep's basic/extended and PCRE (`-P`) regular expressions?

Asked 2021-Jun-15 at 20:55

GNU grep's basic (BRE) and extended (ERE) syntax is documented at https://www.gnu.org/software/grep/manual/html_node/Regular-Expressions.html and PCRE is summarized at man pcresyntax, but there is no explicit comparison. What are the differences between GNU grep's basic/extended and PCRE (-P) regular expressions?

Answered 2021-Jun-15 at 20:55

My research of the major syntax and functionality differences from http://www.greenend.org.uk/rjk/tech/regexp.html:

. in GNU grep does not match null bytes and newlines (but does match newlines when used with --null-data), while Perl, everything except \n is matched.
[...] in GNU grep defines POSIX bracket expressions, while Perl uses "character" classes. I'm not sure on the details. See http://www.greenend.org.uk/rjk/tech/regexp.html#bracketexpression
"In basic regular expressions the meta-characters ?, +, {, |, (, and ) lose their special meaning; instead use the backslashed versions \?, \+, \{, \|, \(, and \)." From https://www.gnu.org/software/grep/manual/html_node/Basic-vs-Extended.html. ERE matches PCRE syntax.
GNU grep \w and \W are the same as [[:alnum:]] and [^[:alnum]], while Perl uses alphanumeric and underscore.
GNU grep has \< and \> for start and end of word.

Perl supports much more additional functionality:

"nongreedy {}" with syntax re{...}?
additional anchors and character types \A, \C, \d, \D, \G, \p, \P, \s, \S, \X. \Z, \z.
(?#comment)
shy grouping (?:re), shy grouping + modifiers (?modifiers:re)
lookahead and negative lookahead (?=re) and (?!re), lookbehind and negative lookbehind (?<=p) and (?


Atomic groups (?>re)
Conditional expression (?(cond)re)
... and more, see man pcresyntax

QUESTION

Comparing Week of Year with "overflow"

Asked 2021-Jun-15 at 20:49

So I want to be able to look at a specific week of the year and look at all data in the preceding and following 6 weeks.

WHERE t1.weeknum >= week-6 AND t1.weeknum <=week+6

So if week is 20, I want to return everything between 14 and 26.

The problem is weeks >=47 and <=6. For instance, if week is 4, I want the range to be 50 through 10. Years are a separate dimension and I am including all data regardless of year.

I think this would be similar to a compass heading. Say you are at 350 degrees and turn right 30 degrees. 350+30 = 20 degree bearing.

I'm using SQL Server Express

ANSWER

Answered 2021-Jun-15 at 20:11

The Modulus operator (%) seems to be what you want. Since you are using the range 1 to 52 to represent week numbers you need to shift the range to 0 to 51 while calculating:

JLEX lexical generator error: unterminated string at the end of the line

Asked 2021-Jun-15 at 20:46

I am generating lexical analyzer with JLEX. I found a regular expression for string literal from this link and used it in .jflex file same of other expressions. but it gives me this error : unterminated string at the end of the line
StringLiteral = \"(\\.|[^"\\])*\"

can anyone help me please, thanks.

ANSWER

Answered 2021-Jun-15 at 20:46

The regular expression you copied is for (f)lex, which uses a slightly different syntax for regular expressions. In particular, (f)lex treats " as an ordinary character inside bracketed classes, so [^"\\] is a character class matching anything other than (^) a quotation mark (") or a backslash (\\).

However, in JFlex, the " is a quoting character, whether outside or inside brackets. So the " in the character class is unterminated. Hence the error message.

So you need to backslash-escape it:

QUESTION

what is the best regular expression to replace non numeric character in a string preceded by certain phrase in python?

Asked 2021-Jun-15 at 20:02

I have to parse lists of names, addresses, etc. that were OCRed and have invalid/incorrect characters in them and on the state postal code I need to recognize the pattern with a 2 character state followed by a 5 digit postal code and replace any non numeric characters in the postal code. I might have OK 7-41.03 at the end of a string I need to remove the hyphen and period. I know that re.sub('[^0-9]+', '', '7-41.03') will remove the desired characters but I need it only replace characters in numbers when found at the end of the string and only if preceded by a two character state wrapped in spaces like OK. It seems if I add anything to the regular expression as far as a lookbehind expression then I can't seem to get the characters replaced. I've come up with the following but I think there must be a simpler expression to accomplish this. Example:
