[SOLVED] Can we insert code in input in Python, format it with f str, and then convert it back to what it really is?

Question

Say I want to input lists in my code.

A list may contain any data type, right.

And say that my sample input is a list that I recognize as squares of counting numbers from 1 to 1000.

Is there a way for me to input that as a list comprehension expression and then rid it of its strings and execute it?

example:

LstStr = '{}'. format(input("Enter list:"))
Lst = ''. join(LstStr)

I enter [i**2 for i in range(1,11)] and of course the result is itself.

Is there a way for me to enter it just lije that yet get python to execute what's inside upon conversion, getting [1, 4, 9, 16, 25, 36, 49, 64, 81, 100]?

Is it doable, if at all, at beginner level? Or should we define a function for this? Should I think more and come back?

Answer 1

LstStr = eval('{0}'. format(input("Enter list:")))
#Lst = ''. join(LstStr)
print(LstStr)

Like this?

Jayakrishna🇮🇳 Oh no I just meant I lost my self control a bit, because of excitement.
To lose it usually has a negative connotation, I guess, but it's great, you're great, eval is great, but me is not so great, is all I mean :-)

Why sorry, what you lose? use of eval()?

Anyways you're welcome.....

Jayakrishna🇮🇳 My head, I guess lol, I refrain from pictured emojis normally but words weren't enough, because this is crazy, I was expecting people to say "no" I guess, and with mad speed, you knew what I was asking, and said "yes, you can do it"
eval is kung fu. I hope I can stick my claws to this language, it seems so fun
