What, if anything, is wrong with this code?

#the teacher's version

CurrentYear $=2020$

myYear $=$ input $("$What year were you born $")$

myAge $=$ CurrentYear $-$ int $($myYear$)$

print$("$Your age is $"+$ str$($myAge$))$

There is a syntactical error and will not run

There is a logical error in the code and will not run

Variable is not defined

Nothing, it works perfectly fine
