OP solved it, closing

Not a kata issue.

It is not a Kata issue. CW server had lots of issues back then.

Choose an appropriate language and language version from above the code section.

By the way, it's a CW problem and not a kata problem, so it's not an issue.

i have provided two example test,,,, can you help me with generating random test... Is there a way to do that

And no name. And a function name that doesn't adhere to camelCase convention.

No random tests. No example tests either.

how to optimize the code... this is fifth kata where my code is being rejected because of my code taking too long for execution.... please help

The instructions ask to return "true" or "false", this is not possible in Python.
Not sure if it works like this, but can the Python-instructions be changed to read "True" and "False".

Additionally, a portion of a string (to me) is equivalent to a slice, i.e. word[2:5], as far as I understand this exercises asks if str2 could be built from characters taken from str1 (without repeats, two "x"s in str2 require (at least) two "x"s in str1 one).
Maybe we could work on the wording a bit?

The test cases are already locked :( The best I can do is to update in the descriptions what you should do in the JS version.

It's an old kata bug :( Because the test cases are already locked I've updated in the descriptions what you should do.
