Hi,
How to check if something is a list or a dictionary or just a string?
Eg:
for item in self.__libVerDict.itervalues():
self.cbAnalysisLibVersion(END, item)
where __libVerDict is a dictionary that holds values as strings or
lists. So now, when I iterate this dictionary I want to check whether
the item is a list or just a string?
if isinstance(item,basestring):
# it's a string
...
else: # it should be a list
# typically you don't have to check it explicitly;
# even if it's not a list, it will raise an exception later anyway
if you call a list-specific method
HTH,
George

Working With Unicode Strings
Thankfully, everything in Python is supposed to treat Unicode strings
identically to byte strings. However, you need to be careful in your own
code when testing to see if an object is a string. Do not do this:
if isinstance( s, str ): # BAD: Not true for Unicode strings!
Instead, use the generic string base class, basestring:
if isinstance( s, basestring ): # True for both Unicode and byte strings
