That’s because num is a Char, i.e. the resulting values are the ascii value of that char. This will do the trick: val txt = “82389235” val numbers = txt.map { it.toString().toInt() } The map could be further simplified: map(Character::getNumericValue)
The pandas method is to use the vectorised str.normalize combined with str.decode and str.encode: In [60]: df[‘Country’].str.normalize(‘NFKD’).str.encode(‘ascii’, errors=”ignore”).str.decode(‘utf-8’) Out[60]: 0 Aland Islands 1 Aland Islands 2 Albania 3 Albania 4 Albania Name: Country, dtype: object So to do this for all str dtypes: In [64]: cols = df.select_dtypes(include=[np.object]).columns df[cols] = df[cols].apply(lambda x: x.str.normalize(‘NFKD’).str.encode(‘ascii’, errors=”ignore”).str.decode(‘utf-8’)) df … Read more
The Character class of Java API has various functions you can use. You can convert your char to lowercase at both sides: Character.toLowerCase(name1.charAt(i)) == Character.toLowerCase(name2.charAt(j)) There are also a methods you can use to verify if the letter is uppercase or lowercase: Character.isUpperCase(‘P’) Character.isLowerCase(‘P’)
You don’t get the character in the editor, because you can’t find it in text editors. #FEFF or #FFFE are so-called byte-order marks. They are a Microsoft invention to tell in a Unicode file, in which order multi-byte characters are stored. To get rid of it, tell your editor to save the file either as … Read more
In Swift 4 it is really simple, just use dropFirst(n: Int) let myString = “Hello World” myString.dropFirst(6) //World In your case: website.dropFirst(6)
You can do this in one line. For example, this counts the number of spaces: NSUInteger numberOfOccurrences = [[yourString componentsSeparatedByString:@” “] count] – 1;
I think that what he wants is to have a string split into substrings of size 4. Then I would do this in a loop: List<String> strings = new ArrayList<String>(); int index = 0; while (index < text.length()) { strings.add(text.substring(index, Math.min(index + 4,text.length()))); index += 4; }
