问题 If I run this code: s.translate(str.maketrans({'as': 'dfg', '1234': 'qw'})) I will get: ValueError: string keys in translate table must be of length 1 Is there a way to replace multiple characters at once using str.translate ? Docs says I can use codecs for flexible approach, but I can't find out how. If no, what can be done instead then? 回答1: No . str.translate can be used solely to replace single characters. The replacement strings can be of any length, but the keys must be a single

问题 This is a follow-up to a previous question I had asked. For that question, I received an excellent answer by @markp-fuso demonstrating the use of an array of search patters for sed to perform a particular substitution task. In this question, I would like to perform the same find and replace task of replacing all forms of pow(var,2) with square(var) but I would like to do this by using a regex variable. The sample input and output files are below: InputFile.txt: pow(alpha,2) + pow(beta,2) (3

问题 I am trying to replace every with --[[RANDOMNUMBER and textbox1 Text]] , but how do I select a new number for each replace, so it's not always 241848 or such? Random random = new Random(); string replacing = " --[[" + random.Next() + textBox1.Text + "]] "; string output = richTextBox1.Text.Replace(" ", replacing); 回答1: Use Regex.Replace(String, String, MatchEvaluator) instead. It takes a MatchEvaluator callback function where you can pull the next random number: Random random = new Random();

For example [text1] [[text2] [text3] should result in ${text1} [${text2} ${text3} How can I accomplish that with regex in Javascript? I wrote something like this someString = someString.replace(/\[/g, "${"); someString = someString.replace(/]/g, "}"); But it doesn't work for my problem, it just replaces every

问题 I have one of my passwords commited in probably few files in my Git repo. Is there some way to replace this password with some other string in whole history automatically so that there is no trace of it? Ideally if I could write simple bash script receiving strings to find and replace by and doing whole work itself, something like: ./replaceStringInWholeGitHistory.sh "my_password" "xxxxxxxx" Edit: this question is not a duplicate of that one, because I am asking about replacing strings
