I am not able to understand why I am getting a Type Error for the following statement
log.debug('vec : %s blasted : %s\n' %(str(vec), str(bitBlasted)))
type(vec) is unicode
bitBlasted is a list
I am getting the following error
TypeError: 'str' object is not callable
Either as Collin said, you could be shadowing the built-in str:
>>> str = some_variable_or_string #this is wrong
>>> str(123.0) #Or this will happen
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'str' object is not callable
One solution would be to change the variable name to str_ or something. A better solution would be to avoid this kind of Hungarian naming system -- this isn't Java, use Python's polymorphism to its fullest and use a more descriptive name instead.
Another possibility is that the object may not have a proper __str__ method or even one at all.
The way Python checks for the str method is:-
__str__ method of the class__str__ method of its parent class__repr__ method of the class__repr__ method of its parent class<module>.<classname> instance at <address> where <module> is self.__class__.__module__, <classname> is self.__class__.__name__ and <address> is id(self)Even better than __str__ would be to use the new __unicode__ method (in Python 3.x, they're __bytes__ and __str__. You could then implement __str__ as a stub method:
class foo:
...
def __str__(self):
return unicode(self).encode('utf-8')
See this question for more details.
zip functions just return an iterable (most likely a list or tuple)? They shouldn't have any problem with their str method.
__repr__() or one of object's methods...As mouad said, you've used the name str somewhere higher in the file. That shadows the existing built-in str, and causes the error. For example:
>>> mynum = 123
>>> print str(mynum)
123
>>> str = 'abc'
>>> print str(mynum)
