Basically, I want to generate truth table list of values using Python. For instance, if I have the following values: [0, 1], I want the following list to be generated: [(0, 0), (0, 1), (1, 0), (1, 1)] If I want my table to have three inputs, then the following list should be generated: [(0, 0, 1), (0, 1, 0),

How to create multiple combinations of columns from a pandas dataframe?
I’ll illustrate my problem with a drawing: I have a pandas dataframe with 13 columns of 6 different types. Then I randomly want to take one of each type and create a new table to perform subsequent analyses. So in the end I want to create (3 choose 1) * 1 * (2 choose 1) * (2 choose 1) *
Can Python generate list of all possible part numbers with given criteria?
I am new to Python. As in really new, just venturing if I can use this language in my work. Can Python generate all the possible part numbers from this list? Condition: Characters are ordered It can have ERJ3RBD1002V, but not 3RERJBD1002V. Thank you so much. PartNumbers Answer Yes it can, except for the resis…
recursive implementation of sum to target Python
I have the following method that, given a target integer, generates all ways to create that integer from an ordered row of integers, subject to the condition that the column index (starting from one) multiplied by the number sums to the target for each row. Below is some code that achieves this. Notice that a…
Get all possible combinations between two lists, including multiple connections
With I get the 16 possible individual combinations of the lists l1 and l2, [(1,1), (1,2), … ] etc. Is there a way to also get combinations that ‘connect’ the lists in multiple ways? For example, I could have the following combinations [(1,1), (2,3)], [(1,3), (2,4), (3,2)], and [(1,2), (2,4),…
All tuples of positive integers
How do I create a generator that will return tuples of all combinations of positive integers, example for generating triplets. Answer This code uses a similar approach to Paul Hankin’s, but it’s more general since it will generate tuples of any desired width, not just 3. output The algorithm for c…
The Assignment Problem, a NumPy function?
Since an assignment problem can be posed in the form of a single matrix, I am wondering if NumPy has a function to solve such a matrix. So far I have found none. Maybe one of you guys know if NumPy/SciPy has an assignment-problem-solve function? Edit: In the meanwhile I have found a Python (not NumPy/SciPy) i…
How do I generate all permutations of a list?
How do I generate all the permutations of a list? For example: Answer Use itertools.permutations from the standard library: Adapted from here is a demonstration of how itertools.permutations might be implemented: A couple of alternative approaches are listed in the documentation of itertools.permutations.
