HW$1-3$

Write a function called sum$\_$concat $($my$\_$dictionary$)$ that takes in a dictionary my$\_$dictionary as an argument and returns a tuple containing the sum of all the values in the dictionary and the concatenation of all the keys in the dictionary as a string. Use the $.$items $()$ method to iterate through the key$-$value pairs of the dictionary.

Test case:

$m{y}_d$ict $=\{a^{\text{'}}$:$1,{?}^{\text{'}}{b}^{\text{'}}$:$2,{?}^{\text{'}}{c}^{\text{'}}$:$3\}$

result $=su{m}_c$oncat $(m{y}_d$ict $)$

result # Output: $(6,{?}^{\text{'}}ab{c}^{\text{'}})$

$[]$ # your solution

$$ HW$1-4$b

Create a function named remove$\_$duplicates $($ lst$)$ that takes a list of integers $($ lst$)$ as its input and returns a new list with any duplicate integers removed. The returned list should be in the same order as the original list.

Test case:

$origina{l}_l$ist $=[1,2,3,2,4,1,5,6,7,8,5,9]$

$remov{e}_d$uplicates$(origina{l}_l$ist$)$ #$[1,2,3,4,5,6,7,8,9]$
