Fill ____ parts of the implementation below. sum_of_list function takes a list as argument and calculates the sum of values in the list. If some element in the list can not be converted to a numeric value, it should be ignored from the sum.
def sum_of_list(values):
____ = 0
for val in values:
____:
numeric_val = float(val)
____ ____ as e:
____
____ += numeric_val
return ____
list1 = [1, 2, 3]
list2 = ["1", 2.5, "3.0"]
list3 = ["", "1"]
list4 = []
list5 = ["John", "Doe", "was", "here"]
nasty_list = [KeyError(), [], dict()]
assert sum_of_list(list1) == 6
assert sum_of_list(list2) == 6.5
assert sum_of_list(list3) == 1
assert sum_of_list(list4) == 0
assert sum_of_list(list5) == 0
assert sum_of_list(nasty_list) == 0
Implement verify_short_string function which takes a single string as argument. If the length of the input string is more than ten characters, the function should raise TooLongString exception (note: you have to create TooLongString yourself). The function does not have to return anything.
# Your implementation here
# These should not raise
verify_short_string("short")
verify_short_string("10 chars")
# This should raise
try:
verify_short_string("this is long")
except TooLongString as e:
# This is ok
pass
else:
# This means that there was no exception
assert False
