# Question 1: DNA translation function
The file ***convert.txt*** contains 64 codons and the residues these codons normally encode.
Give you a sequence, translate the DNA to protein and print the protein string.

def translate_dna(dna):
    #write something

input_dna = "TCACGACGCGTATATGCATGCGCAGTGCGGCTTTTGAATAAAAGGGGGACATTCGAT"

print("DNA sequence: " + input_dna)
output_protein = translate_dna(input_dna)
print("Protein sequence: " + output_protein)


# Question 2: make change for 18763 (找零錢)

You make change for 18763, and just return the minimun amount of coin and bill.

def return_change( money,coin_list ):
    coin_count=[]
    #write something


    return coin_count

    
money=18763
coin=[1000,500,100,50,10,5,1] #bill_and_coin_list

print("coin list:\t",coin)
print ( "coin you return:\t",return_change(money,coin)  )
#1000*18+ 500*1+ 100*2+ 50*1+ 10*1+ 5*0+ 1*3=18763

Hint:
取餘數%, example: 10%3=1, 7%4=3
取商//, example: 10//3=3, 7//4=1

# Question 3: return medium
Please write a function that takes a list to calculate and return its medium. Use the following assertions to test your function:

def my_medium(numbers):
    #write something


numbers = [50.9, 50.3, 48.7, 89.2, 60.0, 74.0, 54.2, 101.6, 84.9, 82.1, 79.4, 93.8]
assert my_medium(numbers) == 76.7

:::warning
Note:
Consider the amount of the numbers.
:::
# Question 4: GC content
Given three DNA sequences, dna_seqs = ["ACGATGTTGCT", "TATTAGTGTCGGCCGCACCGGG", "GTAGGATGATTGT"]

Please write a program with a loop in the main program to compute the GC content of them. The computation of GC contents must be done with a user-defined function.

def get_gc_content(???):
    #write something

dna_seqs = ["ACGATGTTGCT","TATTAGTGTCGGCCGCACCGGG","GTAGGATGATTGT"]
        
for ??? in ???:
    #write something
