If I define a dictionary where one or more of the values is also a
dictionary, e.g.:
my_dict={"a":"s tring", "b":"string ", "c":{"x":"0","y ":"1"},
"d":"string "}
How can I use the output of type() so I can do one thing if the value
is a string, and another if the value is a dictionary?
i.e., I'd like to define a loop like this, but I'm not sure of the
syntax:
for key, value in my_dict.items() :
if type{value) is <type 'dict'>:
# do the dictionary logic
elif type(value) is <type 'str'>:
# do the string logic
# etc 2 1384

.... is str
# do the string logic
For built-in types without a built-in name, either import the types
module or just make one yourself with type().
>>func = type(lambda:1) func
<class 'function'>
>>bif = type(abs) bif
<class 'builtin_functi on_or_method'>
For userclass instances, use the userclass.

You're searching for "isinstance " (or possibly issubclass)
for key, value in my_dict.items() :
if isinstance(valu e, dict):
# do the dictionary logic
elif isinstance(valu e, str): # use basestring for str & unicode
# do the string logic
Or, if you _must_ use type:
if issubclass(type (value), dict):
# do the dictionary logic
elif issubclass(type (value), str):
# do the string logic

Does anyone know how to use VBA to relink tables between two MS Access
databases? We have two databases, one with VBA code and the other with
data tables. The tables are referenced by linked tables in the database
where the code resides. If we move the database with the data tables to
a new directory, the links are no longer valid.
I tried to update the links by changing the Connect property and refreshing:

Hello there,
I have a front end database that I have recently made very many changes
to to allow off-line use. I keep copies of the databases on my hard
drive and link to them rather than the live databases on the network.
Is there a way, via code, when I get back in-house from being on the
road to click a button, and select the backends I want to link to?
I would want to delete all the current links and link to the "live"

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

For most users, this new feature is actually very convenient. If you want to control the update process,...
