问题 I have a url that looks like this : http://mysite.com/1/2/Simpson and I want to create a variable that contains just Simpson... Not sure how to do it here... I have: var myvar = window.location.pathname and have tried something using substring, but can't seem to get it to work? 回答1: this may work, but you might as well use the string window.location.href, not the object window.location (which contains many different objects within it): var dirs = window.location.href.split( '/' ); however,

I already have the solution for sed: s/^1\([0-9]\{10\}\)$/\1/ , I need to make this work with awk . Edit for input and output example. Input: 10987654321 2310987654321 1098765432123 (awk twisted and overcomplicated syntax) Output: 0987654321 2310987654321 1098765432123 Basically

问题 This does not need to necessarily be done in pandas but it would be nice if it could be done in pandas. Say I have a list or Series of strings: ['XXY8779','0060-19','McChicken','456728'] And I have another list or Series which contains sub-strings of the original like so: ['60-19','Chicken','8779','1124231','92871','johnson'] And this would return something like: [True, True, True, False] I'm looking for a match that is something like: ^[a-zA-Z0-9.,$;]+ < matching string in other list > So in

问题 Say I have a list of strings ["rdfa", "gijn", "ipqd"] and have a variable containing the string "and", how would I be able to check if "and" is in the list? To make this more clear think of the list as a word search: rdfa gijn ipqd I see the vertical word "and", but how would I be able to check if the word "and" is in the list? Finding horizontal words was much easier, but finding a vertical word is confusing me. I was thinking possibly that I would need to find if the first letter of "and"
