'Embedding executable python script in python string
If you are a bash/posix sh wizard you will know the $(command substition) feature in bash, which could even be inserted in a string. For example,
$ echo "I can count: $(seq 1 10 | tr -d '\n')"
I can count: 12345678910
You can imagine all wild things to do with this, especially to make a dynamically formed string. No need to do if..else block outside the string; just embed the code inside! I am s spoiled by this feature. So here's the question: in python, can we do something similar? Is there one person already devising a module to accomplish this task?
(Just a side comment: admittedly having this kind of feature is powerful but also opening yourself to a security risk. The program can be vulnerable to code injection. So think thoroughly before doing this especially with a foreign string coming from outside the code.)

See the built-in eval() function.
Solution 3:[3]
Are you looking for an fstring:
Instead of starting the string with '
We start the string with f'
And whenever we want to embed any script we just put inside these: {}
