Find all combinations of strings up to given character length

Asked 2021-Jun-14 at 23:04

I've got a list of strings, for example: ['Lion','Rabbit','Sea Otter','Monkey','Eagle','Rat']

I'm trying to find out the total number of possible combinations of these items, where item order matters, and the total string length, when all strings are concatenated with comma separators is less than a given length.

So, for max total string length 14, I would need to count combinations such as (not exhaustive list):

Lion
Rabbit
Eagle,Lion
Lion,Eagle
Lion,Eagle,Rat
Eagle,Lion,Rat
Sea Otter,Lion
etc...

but it would not include combinations where the total string length is more than the 14 character limit, such as Sea Otter,Monkey

I know for this pretty limited sample it wouldn't be that hard to manually calculate or determine with a few nested loops, but the actual use case will be a list of a couple hundred strings and a much longer character limit, meaning the number of nested iterations to write manually would be extremely confusing...

I tried to work through writing this via Python's itertools, but keep getting lost as none of the examples I'm finding come close enough to what I'm needing, especially with the limited character length (not limited number of items) and the need to allow repeated combinations in different orders.

Any help getting started would be great.

Issue with the last line

plot takes x values and y values as as first and second arguments
here you give mixed values i.e. [x0, y0] and [x2, y2] instead of [x0, x2] and [y0, y2]
this works for first two lines because your values form a symmetric matrix for first two pair of rows in data

I hope you understand the explanation

You need to restructure the data to make array of x values and y values, try:

Seaborn FacetGrid multiple page pdf plotting

Asked 2021-Jun-14 at 17:37

I'm trying to create a multi-page pdf using FacetGrid from this (https://seaborn.pydata.org/examples/many_facets.html). There are 20 grids images and I want to save the first 10 grids in the first page of pdf and the second 10 grids to the second page of pdf file. I got the idea of create mutipage pdf file from this (Export huge seaborn chart into pdf with multiple pages). This example works on sns.catplot() but in my case (sns.FacetGrid) the output pdf file has two pages and each page has all of the 20 grids instead of dividing 10 grids in each page.

You are missing the col_order=cols argument to the grid = sns.FacetGrid(...) call.

Just a guess: it's because you're removing while iterating.

It is sometimes tempting to change a list while you are looping over it; however, it is often simpler and safer to create a new list instead.

You can use a list comprehension instead (it's even more efficient):

Install itertools

You can download it from GitHub.
Rust is installed and managed by the rustup tool. Rust has a 6-week rapid release process and supports a great number of platforms, so there are many builds of Rust available at any time. Please refer rust-lang.org for more information.

Support

For new features, please first consider filing a PR to rust-lang/rust, adding your new feature to the Iterator trait of the standard library, if you believe it is reasonable. If it isn't accepted there, proposing it for inclusion in itertools is a good idea. The reason for doing is this is so that we avoid future breakage as with .flatten(). However, if your feature involves heap allocation, such as storing elements in a Vec<T>, then it can't be accepted into libcore, and you should propose it for itertools directly instead.
