string-comparison

问题 For Eg: When I compare two strings with == operator after I call intern() method it returns true. String name = "Wahab"; // in string literal pool String fullName = new String("Wahab"); // new string in heap String f = fullName.intern(); // pushing into string literal pool System.out.print(name == f); // **true** Using Concat and invoke intern(), == operator returns true. String name = "Wahab".concat("Shaikh"); // concat with new string String fullName = name.intern(); // invoke intern to

问题 I'm attempting to compare two strings with is . One string is returned by a function, and the other is just declared in the comparison. is tests for object identity, but according to this page, it also works with two identical strings because of Python's memory optimization. But, the following doesn't work: def uSplit(ustring): #return user minus host return ustring.split('!',1)[0] user = uSplit('theuser!host') print type(user) print user if user is 'theuser': print 'ok' else: print 'failed'

问题 I am trying to replace strings in one list with strings in another list. strlist = ['D-astroid 3-cyclone', 'DL-astroid 3-cyclone', 'DL-astroid', 'D-comment', 'satellite'] to_match = ['astroid 3-cyclone', 'D-comment', 'D-astroid'] Expected Output: str_list = ['astroid 3-cyclone', 'astroid 3-cyclone', 'D-astroid', 'D-comment', 'satellite'] and also output a dictionary containing the mappings dict = {'astroid 3-cyclone':['astroid 3-cyclone', 'astroid 3-cyclone'], 'D-comment':'D-comment', 'D

问题 For example if I have... string a = "personil"; string b = "personal"; I would like to get... string c = "person[i]l"; However it is not necessarily a single character. I could be like this too... string a = "disfuncshunal"; string b = "dysfunctional"; For this case I would want to get... string c = "d[isfuncshu]nal"; Another example would be... (Notice that the length of both words are different.) string a = "parralele"; string b = "parallel"; string c = "par[ralele]"; Another example would

问题 How this can be ? (This is taken from the immediate window in VS2008) ?string.Compare("-", "+") -1 ?string.Compare("-0", "+0") 1 回答1: From the remarks on String.Compare (emphasis mine): The comparison uses the current culture to obtain culture-specific information such as casing rules and the alphabetic order of individual characters. For example, a culture could specify that certain combinations of characters be treated as a single character, or uppercase and lowercase characters be compared

问题 Context For quite a lot of our CentOS servers I would like to install some monitoring software, the software is based on the CentOS version, I want to check the release version and install software based on that. Issue It seems that the if statements are run successfully without errors while the results never should be true for both or all three if statements. I've looked into the if commands and the tests, it seems that I should use double brackets and single = symbol in bash. I believe that

问题 I'm thinking this has to have a simple answer, but I can't find any examples. I have to compare every member of a list to a list of substrings to see if that member contains a substring, and if it does - return the substring to a third list at the same position as the member of the first list. Example: ListA = {"help me rhonda", "in my room", "good vibrations", "god only knows"} ListB = {"room", "me", "only"} ListC should then should = {"me", "room", null, "only"} I'm an advanced programmer

问题 Is there any function similar to "array_intersect" but it is in mode case-insensitive and ignoring tildes? The array_intersect PHP function compares array elements with === so I do not get the expected result. For example, I want this code : $array1 = array("a" => "gréen", "red", "blue"); $array2 = array("b" => "green", "yellow", "red"); $result = array_intersect($array1, $array2); print_r($result); Outputs gréen and red . In default array_intersect function just red is proposed (normal cause
