The to_dict() method sets the column names as dictionary keys so you’ll need to reshape your DataFrame slightly. Setting the ‘ID’ column as the index and then transposing the DataFrame is one way to achieve this. to_dict() also accepts an ‘orient’ argument which you’ll need in order to output a list of values for each column. Otherwise, a dictionary of … Read more
Yes. Set a reference to MS Scripting runtime (‘Microsoft Scripting Runtime’). As per @regjo’s comment, go to Tools->References and tick the box for ‘Microsoft Scripting Runtime’. Create a dictionary instance using the code below: or Example of use: Don’t forget to set the dictionary to Nothing when you have finished using it.

I’m not sure how exactly you want the formatting to look like, but you could start with a function like this:
Your problem is that you have key and value in quotes making them strings, i.e. you’re setting aKey to contain the string “key” and not the value of the variable key. Also, you’re not clearing out the temp list, so you’re adding to it each time, instead of just having two items in it. To fix your code, try something like: You don’t need to copy … Read more

A dictionary has, by definition, an arbitrary number of keys. There is no “the key”. You have the keys() method, which gives you a python list of all the keys, and you have the iteritems() method, which returns key-value pairs, so Python 3 version: So you have a handle on the keys, but they only really mean sense if coupled to … Read more
has_key was removed in Python 3. From the documentation: Removed dict.has_key() – use the in operator instead. Here’s an example:
It would have the following syntax You can then look things up like
Python 3+: Python 2:
