AI代码解释 >>>'Hello'in'Hello, World'True>>>'Hello'in'Hello'True>>>'HELLO'in'Hello, World'False>>>''in'spam'True>>>'cats'notin'cats and dogs'False 这些表达式测试是否可以在第二个字符串中找到第一个字符串(精确字符串,区分大小写)。 将字符串放入其他字符串中 将字符串放入其他字符串中是...
int("25") is not an integer literal because the integer value is created from a string.When you write large numbers by hand, you typically group digits into groups of three separated by a comma or a decimal point. The number 1,000,000 is a lot easier to read than 1000000....
function NumbersToWords(number) { var numbersArray = [1, 2, 3, 4, 5]; var wordsArray = ["one", "two", "three", "four", "five"]; for (let i = 0; i < numbersArray.length; i++) { number = number.toString().replaceAll(numbersArray[i], wordsArray[i]); } return number;}...
In addition,Python’s strings support the sequence type methods described in the Sequence Types — str, unicode, list, tuple, buffer, xrange section. To output formatted strings use template strings or the % operator described in the String Formatting Operations section. Also, see the re module ...
# Add the non-letters back to the start or end of the word. pigLatin.append(prefixNonLetters + word + suffixNonLetters) # Join all the words back together into a single string: print(' '.join(pigLatin)) 这个循环结束后,我们通过调用join()方法将字符串列表合并成一个字符串。这个字符串被...
