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.
