我需要为环境变量设置密码，但问题是密码包含尖锐符号，当我想使用这个变量时，只显示第一个尖锐符号。例如假设he#l#lo是我的密码，当我将其设置为 时/etc/environment，PASSWORD_API="he#l#lo"我打印它只是显示he并在之后留下字符#。但是当我export PASSWORD_API="he#l#lo"从终端使用时一切正常！通过添加环境变量有什么问题\etc\environment我无法更改密码所以如果你有任何想法请帮助我。谢谢你
我想在python中将一个复杂的字符串写入一个文件，但问题是我的文本本身也有一个命令、双引号和单引号，所以python不能写它并假设它也是一个命令。例如，我想将以下文本写入 file.txt：

我尝试：
result = 'echo "{result}" >> file.txt'.format(result=str(raw_result))
subprocess.Popen(result,
stdout=subprocess.PIPE,
stderr=subprocess.STDOUT,
shell=True)
然后尝试将其更改为 dic：
result = 'echo "{result}" >> /home/parsezan/work/django.txt'.format(result=str({'result': str(raw_result)}))
subprocess.Popen(result,
stdout=subprocess.PIPE,
stderr=subprocess.STDOUT,
shell=True)
但没有人不工作。有什么想法吗？谢谢
我需要更改英特尔图形中的保留热键，以便我可以在 PyCharm 中使用它们。默认情况下Ctrl++ /在 Intel AltGraphic中使用，因此我需要在 Ubuntu 18.04 LTS 中更改它们。windows 只需打开并更改它们，但我在 Ubuntu 中找不到任何明确的方法。因为我是Linux的新手，请以某种方式解释以了解。RightLeftIntel graphic control panel

我是 Ubuntu 社区的新用户。我最近安装了 Ubuntu 18.04。每次我尝试将鼠标移到屏幕右侧时，我的鼠标都不会停在屏幕的末尾，而是会丢失，就像我的屏幕有一个我看不到的扩展。如果我尝试将窗口向右移动到屏幕屏障之外，也会发生同样的事情。
有谁知道为什么会这样，我该如何解决？
