如何在终端中运行一行 Python 命令？

Question

I want to get result of a Python function in terminal.我想在终端中获得 Python function 的结果。

I tried to run the command:我试图运行命令：

$ python3 -m uuid uuid.uuid4().hex

And I expect to see the output be something like: '78cbf0fadaa34ff7ac3f7b965965e207'我希望看到 output 类似于： '78cbf0fadaa34ff7ac3f7b965965e207'

Unfortunately I get error:不幸的是我得到错误：

 -bash: syntax error near unexpected token `('

You were close.你很亲密。

The flag to run a single command is -c and not -m .运行单个命令的标志是-c而不是-m 。
You also need to import uuid so you can use it.您还需要import uuid以便使用它。
You also need to use print() to actually see some output.您还需要使用print()来实际看到一些 output。
Finally the whole passed command has to be in quotes.最后，整个传递的命令必须用引号引起来。

$ python3 -c "import uuid; print(uuid.uuid4().hex)"
