strip

I have a pandas DF that has many string elements that contains words like this: 'Frost ' Which has many leading white spaces in front of it. When I compare this string to: 'Frost' I realized that the comparison was False due to the leading spaces. Although I can solve this by iterating over every element of the pandas DF, the process is slow due to the large number of records I have. This other approach should work, but it is not working: rawlossDF['damage_description'] = rawlossDF['damage_description'].map(lambda x: x.strip('')) So when I inspect an element: rawlossDF.iloc[0]['damage

Is there anyway easier than this to strip HTML from a string using Perl? $Error_Msg =~ s|<b>||ig; $Error_Msg =~ s|</b>||ig; $Error_Msg =~ s|<h1>||ig; $Error_Msg =~ s|</h1>||ig; $Error_Msg =~ s|<br>||ig; I would appreicate both a slimmed down regular expression, e.g. something like this: $Error_Msg =~ s|</?[b|h1|br]>||ig; Is there an existing Perl function that strips any/all HTML from a string, even though I only need bolds, h1 headers and br stripped? Abhinav Gupta Assuming the code is valid HTML (no stray < or > operators) $htmlCode =~ s|<.+?>||g; If you need to remove only bolds, h1's and

How can I strip punctuation except for these characters . = $ ' - € % Since you need to match some Unicode characters ( € ) it would be sensible to use a regular expression. The pattern \p{P} matches any known punctuation, and the assertion excludes your desired special characters from vanishing: $text = preg_replace("/(?![.=$'€%-])\p{P}/u", "", $text); Here's a neat way to do it: preg_replace("#[[:punct:]]#", "", $target); <? $whatToStrip = array("?","!",",",";"); // Add what you want to strip in this array $test = "Hi! Am I here?"; echo $test."\n\n"; echo str_replace($whatToStrip, "", $test)

We implemented the online service where it is possible to generate PDF with predefined structure. The user can choose a LaTeX template and then compile it with an appropriate inputs. The question we worry about is the security, that the malicious user was not able to gain shell access through the injection of special instruction into latex document. We need some workaround for this or at least a list of special characters that we should strip from the input data. Preferred language would be PHP, but any suggestions, constructions and links are very welcomed. PS. in few word we're looking for

I know that there is an option "-Os" to "Optimize for size", but it has little affect, or even increase the size on some occasion :( strip (or "-s" option) removes debug symbol table, which works fine; but it can only decrease only a small propotion of the size. Is there any other way to go furthur? Apart from the obvious ( -Os -s ), aligning functions to the smallest possible value that will not crash (I don't know ARM alignment requirements) might squeeze out a few bytes per function. -Os should already disable aligning functions, but this might still default to a value like 4 or 8. If

I am using request.path to return the current URL in Django, and it is returning /get/category . I need it as get/category (without leading and trailing slash). How can I do this? >>> "/get/category".strip("/") 'get/category' strip() is the proper way to do this. def remove_lead_and_trail_slash(s): if s.startswith('/'): s = s[1:] if s.endswith('/'): s = s[:-1] return s Unlink str.strip() , this is guaranteed to remove at most one of the slashes on each side. Another one with regular expressions: >>> import re >>> s = "/get/category" >>> re.sub("^/|/$", "", s) 'get/category' 来源： https:/

I am trying to use strip() to trim off the space before and after a string. It works fine for str1 = " abdced " str1.strip() However when I use it inside a function, it is not working: def func(str1): return str1.strip() print func(" abdwe ") It won't trim off any space. Anyone can tell what's happening? Thanks! strip is not an in-place method, meaning it returns a value which must be reassigned like so: str1 = str1.strip() # the string is reassigned to the returned stripped string Three things I see. First, you are not assigning the strip variable to anything, second you are trying to do this

I have a CSV file which I'm reading in like below. I need to get the first word of all the strings. I know how to get first letter but I'm not sure how I can get words. ['diffuse systemic sclerosis', 'back', 'public on july 15 2008'] ['diffuse systemic sclerosis', 'forearm', 'public on may 9 2014'] I want my output to be diffuse back public forearm You can use a list comprehension , and split() function : >>> l=['diffuse systemic sclerosis', 'back', 'public on july 15 2008'] >>> [i.split()[0] for i in l] ['diffuse', 'back', 'public'] You can use comprehension >>> l = [['diffuse systemic

Please help! I need to strip the following code so that it only uses the "value" part $<object width="360" height="226"><param name="movie" value="http://www.youtube.com/v/IkZuQ-aTIs0"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/IkZuQ-aTIs0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="360" height="226"></embed></object> So in this case it would strip it down to http://www.youtube.com/v/IkZuQ-aTIs0 The catch is that this is dynamic so it is
