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. What other code within the Tic$-$Tac$-$Toe program would be a good set of statements to turn into a function?

a$.)$

Changing validMove from False to True:

validMove$=$True;

b$.)$

Decrementing the column and row:

col $-=1$

row $-=1$

c$.)$

Players selecting a column and row:

while $($col $<1$ or col $>3)$:

col $=$ int$($input$($playerTurn $+"$ player, select a column $1-3$: $"))$

if $($col $<1$ or col $>3)$:

print$("$The column must be between $1$ and $3.")$

while $($row $<1$ or row $>3)$:

row $=$ int$($input$($playerTurn $+"$ player, select a row $1-3$: $"))$

if $($row $<1$ o$)$r row $>3)$:

print$("$The row must be between $1$ and $3.")$

d$.)$

Changing playerTurn from X to O:

if playerTurn $=="$X$"$:

playerTurn$="$O$"$

else:

playerTurn$="$X$"$
