CS50 - Python 中的 DNA 分配

Question

I'm kinda stuck on DNA cs50's pset, how can I load the text into a variable, get the headers from the first row and start counting this is my code so far:

with open(sys.argv[1]) as csvfile:
    csv_reader = csv.reader(csvfile)
    csv_list = list(csv_reader)

STR = 
for STR in csv_list[0][1:]:
    if 'AGAT' in csv_list[STR]:
        count += 1

Answer 1

What exactly are you stuck on? To load the headers into a variable, you can use STR = csv_list[0][1:] so that you have a list of the patterns.

You can then use this list variable to do your comparisons (I recommend using regular expressions to just get more comfortable with it).

Answer 2

You can write

variable = open('file_path', 'r')

variable = variable.read()
