Python Code: # Define a function 'reverse_string_words' that takes a string 'text' as input.# The function splits the input text into lines, reverses the words within each line, and returns the result.defreverse_string_words(text):forlineintext.split('\n'):return(' '.join(line.split...
如果您曾经尝试过反转 Python 列表,那么您就会知道列表有一个方便的方法,称为原位.reverse()反转底层列表。由于字符串在 Python 中是不可变的,因此它们不提供类似的方法。 但是,您仍然可以使用.reverse()模仿list.reverse(). 您可以这样做: >>> >>>fromcollections import UserString>>>classReversibleString(UserS...

Output: "example good a" Explanation: You need to reduce multiple spaces between two words to a single space in the reversed string. 1. 2. 3. Note: A word is defined as a sequence of non-space characters. Input string may contain leading or trailing spaces. However, your reversed string...
defreverse_string1(s):"""Return a reversed copyof `s`"""returns[::-1]>>>reverse_string1('TURBO')'OBRUT' 新手第一次遇到列表切片时可能很难理解列表切片。 我觉得使用Python的切片功能来反转字符串是一个不错的解决方案,但是对于初学者来说可能很难理解。
1 #方法三,用reverse()方法对列表操作取反,join()方法使列表转换为字符串 2 str = list(input('input a string:')) 3 str.reverse()#该方法没有返回值,若打印则出现None,但会对列表元素进行反向排序。因此用print(list)来查看排序即可 4 print(''.join(str)) ...

Python provides the built-in string (str) data type to handle textual data. Other programming languages, such as Java, have a character data type for single characters. Python doesn’t have that. Single characters are strings of length one. In practice, strings are immutable sequences of char...
