使用来自 bash 的变量输入执行 python 的一行

Question

I want to write one line of python and wrap in such a way than it will run from bash. I looked into it and the idea seemd possible but, I'd specifically like to incorporate a variable input.

As an illustrative example; Here's what worked:

python -c "print('my favorite number to itself is '+str(5**5))"

However, I'd like to have a variable input so I tried to pipe one in, but the following doesn't work:

5 | python -c "print('my favorite number to itself is '+str($1**$1))"

What can I do to keep it simple, keep it one line, and add a variable input?

Answer 1

You could do:

i=5; python -c "print('my favorite number to itself is '+str($i**$i))"

Answer 2

With xargs:

echo 5 | xargs -I {} python -c "print('my favorite number to itself is '+str({}**{}))"
