Did not understand the test about expecting exeptions

print("A")
try:
    result = "test" + 5
    print("B")
except ValueError:
    print("C")
except TypeError:
    print("D")
else:
    print("E")
print("F")

OMG. I stared at this for 10 minutes, didn't figure it out. I was already confused by the first line, why is it there, I don't think it's of any impact on the exercise? anyway, moved on: try: analyses the code I know could throw an error, and the error is clear, string + number. The rest of the code I really didn't understand. Thank you in advance to whoever can explain this :)

Here are the steps:

print("A")  #1 print A
try:  #2 enter try
    result = "test" + 5  #3 raise TypeError adding mixed types
    print("B")
except ValueError:
    print("C")
except TypeError:  #4 jump to TypeError
    print("D")  # print D
else:  # skip else due to error
    print("E")
print("F")  #5 print F

So, A, D, F
