我有一个特定的格式,我想将元组转储到YAML文件中。我尝试运行以下代码将元组转储到YAML文件中。在下面的代码中,我尝试使用append()将一对元组(x,y)添加到列表中。在此之后,我会将列表转储回YAML文件。我的问题是,当我转储回YAML文件时,是否可以保持文件的特定格式不变? import ruamel.yaml
def addObstacles():
yaml = ruamel.yaml.YAML()
with open('input.yaml') as f:
doc = yaml.load(f)
x = 5

我刚刚通过apt-get在Ubuntu10.04安装了电子书管理工具,但是我发现它是当前版本背后的一个主要版本,所以我决定直接从源代码中重新安装它。
当我卸载打包版本时,apt向自动删除队列添加了大量依赖项,并且当我从源代码中安装了新版本的量程时,它不知道它依赖于这些包。
现在我基本上有了我想要的所有库,但是它们仍然在自动删除队列中。

我想在mac上的虚拟环境中安装python-Qt4库。我在运行python2.7。建议使用:
sudo apt-get install python-qt4
对于mac和linux用户,但这对我来说是失败的,因为mac没有apt-get命令。所以我尝试使用brew install python-qt4,但是我得到了以下错误消息:

我是码头新来的。有一件事让我很困惑,当我在Docker中打印哪条python的输出时,它指向系统的python,尽管我已经提到python3.7作为基本映像,所以它应该指向图像python,对吗?
