python code for import sys

# todo $1$: create a string with your matric card number with name $`$S$`.$ Extract only the numeric digits and print.

# todo $2$: Convert string $`$S$`$ into a list with name $`$L$`$

# todo $3$: Convert string $`$S$`$ into a tuple with name $`$T$`$

mem$\_$size$\_$L $=$ sys$.$getsizeof$($L$)$

mem$\_$size$\_$T $=$ sys$.$getsizeof$($T$)$

# todo $4$: compare $`$mem$\_$size$\_$L$`$ and $`$mem$\_$size$\_$T$`,$ see which data structure is more memory efficient
