converting a set() to an int python
So my question is how can you (or if it can be done at all) convert data type of set to an integer? for example: (IS A TOY EXAMPLE TO EXPLAIN WHAT I’M TRYING TO DO) Output: <class ‘int’> So any assistance in the conversion of a set() to an int would be greatful. I have seen this how-can-i-convert-a-set-of-numeric-strings-to-a-set-of-integers which
Generating Maximal Subsets of a Set Under Some Constraints in Python
I have a set of attributes A= {a1, a2, …an} and a set of clusters C = {c1, c2, … ck} and I have a set of correspondences COR which is a subset of A x C and |COR|<< A x C. Here is a sample set of correspondences COR = {(a1, c1), (a1, c2), (a2, c1), (a3, c3), (a4,
Why set automatically unpacks range, but list doesn`t? How this can be used?
I create list and set with range. Set unpacks range, list doesn`t Answer The reason why it doesn’t unpack is because my_list is only putting two brackets next to it, if you do that with set it will be the same: But if you do list(…) it will unpack:
Unique lists within list of lists if those lists have list as one of the elements
If I have: What would be the best way to get: If I try: I get TypeError: unhashable type: ‘list’. I don’t want to remove all layers of nesting, because that would just combine everything into one list: Output: If two instructors have the same count (i.e. 3 in this case), then only one 3 remains because it’s a set,
How to add() runtime input in a set in python?
Problem I am trying to add() elements in a set at run time using a for loop: Surprisingly, l1 is a set but, when I go on add() -ing elements to my set l2 in a loop I get : TypeError: unhashable type: ‘list’ Research Effort: Here are other ways I have tried to add() elements to set l2 and
Equality between frozensets
Example: Frozen sets are immutable. I would expect that equality between immutable objects should by determined by order, but here obviously that is not the case. How can I discard frozensets with same elements and different order, without casting to different type? Answer The short answer is you can’t, since as pointed out in the comments, sets and frozensets are
Why does Python assign None if you add a variable to a set while assigning it
Instead of adding a variable to a set correctly, e.g.: I just accidentally coded: While I appreciate that this is not how you should add items to a set, it surprised me that the above resulted in set_to_add_to taking the value None. I couldn’t work out why that would happen: it seems analogous to int_variable = int_variable + 5, which
How do I find the keys in one dictionary that do not have a counterpart in another dictionary?
In Python, how do I find the keys in one dictionary that do not have a counterpart in another dictionary? The practical problem is that I have a dictionary of people that enrolled and a dictionary with their daily participation and I am trying to find the people that enrolled but did not participate, or are in the enrollments dictionary
Why does a set display in same order if sets are unordered?
I’m taking a first look at the python language from Python wikibook. For sets the following is mentioned: We can also have a loop move over each of the items in a set. However, since sets are unordered, it is undefined which order the iteration will follow. and the code example given is : Output: When I run the program
