User input fractions or operations

I want to ask for an input in which the user is able to introduce a fraction

like:

x=input('Hi: ')

Hi: 1/3

x=

0,3333333333333

Can I do that?

Yes. When you use input() without the 's' option, then whatever the user inputs will be executed and the result will be stored in the output variable.

For example the user could also have input sinpi((1:10)/7) and the expression would be evaluated and the results put into the variable.

The variable will not have access to the input characters in this case. If you need access to the input characters then you need to use the 's' option.
