I'm trying to get a substring in a for loop. For that I'm using this:
for peoject in subjects:
peoject_name = peoject.content
print(peoject_name, " : ", len(peoject_name), " : ", len(peoject_name.split('-')[1]))
I have some projects that don't have any "-" in the sentence. How can I deal with this?
I'm getting this issue:
builtins.IndexError: list index out of range
for peoject in subjects:
try:
peoject_name = peoject.content
print(peoject_name, " : ", len(peoject_name), " : ", len(peoject_name.split('-')[1]))
except IndexError:
print("this line doesn't have a -")
except IndexError.you could just check if there is a '-' in peoject_name:
for peoject in subjects:
peoject_name = peoject.content
if '-' in peoject_name:
print(peoject_name, " : ", len(peoject_name), " : ",
len(peoject_name.split('-')[1]))
else:
# something else
You have a few options, depending on what you want to do in the case where there is no hyphen.
Either select the last item from the split via [-1], or use a ternary statement to apply alternative logic.
x = 'hello-test'
print(x.split('-')[1]) # test
print(x.split('-')[-1]) # test
y = 'hello'
print(y.split('-')[-1]) # hello
print(y.split('-')[1] if len(y.split('-'))>=2 else y) # hello
print(y.split('-')[1] if len(y.split('-'))>=2 else '') # [empty string]
