python编写一个程序：将字符串”I prefer cats to dogs”中的单词进行倒序输出，结果为：”dogs to cats prefer I”

你可以使用Python的内置函数split()将句子分割成单词列表，然后使用列表的reverse()方法反转顺序，最后再使用join()函数将单词连接成新的字符串。以下是实现这个功能的简单代码：
def reverse_words_in_string(input_string):
# 将字符串分割成单词列表
words = input_string.split()

# 反转列表中的单词顺序
words.reverse()

# 使用空格连接单词生成新字符串
reversed_string = ' '.join(words)

return reversed_string

# 测试输入
input_str = "I prefer cats to dogs"
reversed_output = reverse_words_in_string(input_str)
print(reversed_output) # 输出: "dogs to cats prefer I"

在这个例子中，split()函数默认以空格作为分隔符，所以每个单词都是单独的元素。reverse()函数会改变列表元素的顺序，最后join()函数则是利用空格把单词重新组合成一句话。

* What went wrong: Build was configured to prefer settings repositories over

Build配置错误：构建过程优先考虑了settings repositories而非预期的资源。这通常意味着在尝试从settings仓库获取构建所需的组件、依赖项或配置文件时，出现了问题。可能的问题包括：

配置设置有误：settings repositories未正确配置，导致找不到必要的构建配置信息。
网络连接问题：访问settings仓库时遇到网络中断或服务器不可达。
版本冲突：两个或更多仓库中有相同的依赖，但版本不兼容，导致构建失败。
存储库临时故障：settings仓库本身可能正在维护或者存在临时性的技术问题。

为了解决这个问题，可以尝试以下步骤：

检查build.gradle或其他配置文件，确保settings repositories的引用正确。
检查网络连接是否正常。
清理本地缓存，强制从仓库下载最新的依赖。
如果是多个repository引起的冲突，尝试更新到特定版本或显式指定依赖来源。

这些警告是因为你在安装某些 Python 包时，它们在安装过程中将可执行文件安装到了 Python 的 Scripts 文件夹中，但是这个文件夹不在系统的 PATH 环境变量中，因此可能无法直接运行这些可执行文件。
你可以将 C:\Users\86136\AppData\Roaming\Python\Python39\Scripts 添加到系统的 PATH 环境变量中，这样就可以直接在命令行中运行这些可执行文件了。或者，你可以使用 --no-warn-script-location 选项来忽略这些警告。
