Functions can be used to replace multiple code statements that perform essentially the same task with different values. This occurs in the Tic$-$Tac$-$Toe game program within the tutorial. See the printBoard function created there as an example. Functions often need to switch between doing something based on their input, such as offering different queries to a user. What string method could be used to switch between printing "select a column" and "select a row"?

a$.)$

The $.$swapcase$()$ method; for example,

col$\_$or$\_$row $=$ 'column'

print$("$The $\{\}$ must be between $1$ and $3.".$swapcase$($col$\_$or$\_$row$))$

b$.)$

The $.$title$()$ method; for example,

col$\_$or$\_$row $=$ 'column'

print$("$The $\{\}$ must be between $1$ and $3.".$title$($col$\_$or$\_$row$))$

c$.)$

The $.$index$()$ method; for example,

col$\_$or$\_$row $=$ 'column'

print$("$The $\{\}$ must be between $1$ and $3.".$index$($col$\_$or$\_$row$))$

d$.)$

The $.$format$()$ method; for example,

col$\_$or$\_$row $=$ 'column'

print$("$The $\{\}$ must be between $1$ and $3.".$format$($col$\_$or$\_$row$))$
