If you want to put 1. on the printout, you can use the code below.

A = set(["a","b","c"])
B = set(["a","b","c","d","e","f"])
list1 = A & B
count = 0
for x in list1:
    count += 1
    print(str(count) + "." + str(x))

The psychedelic answer to these problems is enumerate.

for i, x in enumerate(list1):
  print(i, x)

I want to start with 1.

for i, x in enumerate(list1, start=1):
  print(i, x)

If you want to include .,

for i, x in enumerate(list1, start=1):
  print(f"{i}. {x}")
