What is the result of this code?

my$\_$first$\_$list $=[\text{'}$a$\text{'},\text{'}$b$\text{'},\text{'}$c$\text{'}]$

my$\_$second$\_$list $=[\text{'}$d$\text{'},\text{'}$e$\text{'},\text{'}$f$\text{'},\text{'}$g$\text{'}]$

my$\_$third$\_$list $=$ my$\_$second$\_$list $+$ my$\_$first$\_$list

my$\_$third$\_$list.pop$()$

my$\_$third$\_$list.sort$()$

print $($my$\_$third$\_$list$)$

$[\text{'}$a$\text{'},\text{'}$b$\text{'},\text{'}$d$\text{'},\text{'}$e$\text{'},\text{'}$f$\text{'},\text{'}$g$\text{'}]$

$[\text{'}$d$\text{'},\text{'}$e$\text{'},\text{'}$f$\text{'},\text{'}$g$\text{'},\text{'}$a$\text{'},\text{'}$b$\text{'}]$

$[\text{'}$a$\text{'},\text{'}$b$\text{'},\text{'}$c$\text{'},\text{'}$d$\text{'},\text{'}$e$\text{'},\text{'}$f$\text{'}]$

An error, because pop is not a method available for lists.
