kandi X-RAY | cracking-the-coding-interview Summary

cracking-the-coding-interview is a C++ library. cracking-the-coding-interview has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

This repo contains C++ and Python solutions for Gayle Laakmann McDowell's Cracking the Coding Interview 6th Edition. Admittedly, there are other GitHub repositories with solutions for this book. But how do you know that their code is actually correct? If it's untested, then you don't!. In this project, every C++ solution has unit tests using the C++ Catch framework, and every Python solution has unit tests using the Python unittest framework. We enforce test correctness automatically using continuous integration servers ensuring that the solutions are made of living code that gets executed and tested on every single commit. To my knowledge, this is the Internet's only solutions repository with this level of testing rigor: >90% automated test coverage means you can reference and contribute solutions with confidence.

QUESTION

Jupyter notebook, working with data for machine learning

Asked 2018-Sep-17 at 18:19

I am pretty new to working with jupyter notebook. I overall like it, although I sometimes get some weird errors that sometimes appear and then sometimes do not. For example, I have a data set that looks like this (showing the .head()):

Now, if I set say volume = data["avg_volume"], and then say volume.head() I get this:

But lets say I delete that line and put it somewhere else, I sometimes will get this error:

...

In your code for data in pnl, you redefined the variable data, so it is no longer a DataFrame and cannot by indexed by a colum name.

And BTW, many bugs like this can be found out when you are trying to produce a minimal, complete, verifiable example. You'll notice that when you remove the for loop this bug is gone.
