The code below does not do what the programmer expects. What is wrong with their code?

How would they fix it$?$

$1$ listOfInts $=[1,2,3,4]$ # Create list with numbers $1-4$

$2$ listOfInts$[1]=3//2$ # Update the $1$st number of list to be $1\mathrm{.}5$

$3$ listOfInts$[4]=1**2$ # Update the $4$th number of list to be $2$

$4$ print$($listOfInts$)$ # Print the list
