let say i have a file with random letters of A, AB, C, CD, AC, A, D, CD, DD, C, B, AB, CD, AB How do i count the occurrence of each individual item.
def occurence(name): infile = open('bloodtype1.txt', 'r') lst = infile.read() infile.close() print(lst.count('AB')) # 3 print(lst.count('CD')) # 2 print(lst.count('DD'))# 1 i know i can do lst.count("AB") it will give me 3 but if i were to do lst.count("A") it would give me 6 what I am having trouble with is just getting the occurrence of the A by itself to give me 1 since there is just one occurrence of it and would need to do the same for c and d with out it counting the them in the occurrence of AC and DD or CD. _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
