python - How can I read individual lines from a CSV file? -


at moment i've got function:

def writer(file_name)     open_file = open(file_name,"r+", newline='')     csv_output = csv.writer(open_file)      csv_output.writerow(student)     open_file.close()

where student is:

"string_1","string_2",int

i'm looking read through file first , check if "string_1" i'm writing matches of "string_1"s written, can't find built-in function lets me read each line , store list.

first, have open file reading, go through file line line , return, if "string_1" found:

def append_student(file_name, student)     open(file_name, "r") f:         line in csv.reader(f):             if line[0] == student[0]:                 return     open(file_name, "a") f:         csv.writer(f).writerow(student)
