As advised, I used some code samples in another forum, but it could not improve the problem. My question is the “typeerror: ‘bool’ object is not iterable” in python – How to solve it?
The command line is:
# this uses bottle py framework and should return a value to the html front-end
@get('/create/additive/<name>')
def createAdditive(name):
return pump.createAdditive(name)
def createAdditive(self, name):
additiveInsertQuery = """ INSERT INTO additives
SET name = '""" + name + """'"""
try:
self.cursor.execute(additiveInsertQuery)
self.db.commit()
return True
except:
self.db.rollback()
return Falseand the result:
Traceback (most recent call last):
File "C:\Python33\lib\site-packages\bottle.py", line 821, in _cast
out = iter(out)
TypeError: 'bool' object is not iterableWhat does the message mean? Can you advise me to fix it? If you have other better answers, leave them in the answer box below.
The cause: I think the cause of this error is your code isn’t iterating the value, but the code receiving it is. You can see that on the traceback:
The solution: To solve this problem, you should return an iterable. I recommend either converting the bool to a string (
str(False)) or enclosing it in a tuple ((False,)).
