My mkdir command /create_directory command always deletes all the files and doesnt really

Code error where list index is out of range when doing command like -p.docx
Code error where list index is out of range when doing command like "python3 edfs.py -create /user/file" Trying to follow instruction of python edfs.py -create which will create a file in the specified path. Note the file is empty and your implementation only needs to add the file name to your emulated file system. No need to add data for the file. The command should report an error if the file already exists. Also command "python3 edfs.py -ls /" should list all files under directory but is unable to due to some error that list object has no attribute keys.

My code does not work right in that when i run create_file- i am unabl.pdf
The code is unable to add multiple files to the same directory or add new directories under an existing one. It replaces existing files instead of adding new ones. Directories can only be created with a trailing slash. The code uses PUT requests instead of POST which may be causing the issues. The user asks how to fix these problems.
How can I make it so my code works so my command line can look like -p (1).docx
How can I make it so my code works so my command line can look like "python3 edfs.py -create /user/file" instead of "python3 edfs.py -create /user file" as it only works with spaces between.

Slick: Bringing Scala’s Powerful Features to Your Database Access
This talk will teach you how to use Slick in practice, based on our experience at EatingWell Media Group. Slick is a totally different (and better!) relational database mapping tool that brings Scala’s powerful features to your database interactions, namely: static-checking, compile-time safety, and compositionality.
Here at EatingWell, we have learned quite a bit about Slick over the past two years as we transitioned from a PHP website to Scala. I will share with you tips and tricks we have learned, as well as everything you need to get started using Slick in your Scala application.
I will begin with Slick fundamentals: how to get started making your connection, the types of databases it can access, how to actually create table objects and make queries to and from them. We will using these fundamentals to demonstrate the powerful features inherited from the Scala language itself: static-checking, compile-time safety, and compositionality. And throughout I will share plenty of tips that will help you in everything from getting started to connection pooling options and configuration for use at scale.

While Slick has some learning curve and documentation issues, it allows defining queries in a clear, type-safe way that is translated to efficient SQL.
12-OO-PHP.pptx
1. Object-oriented PHP allows grouping related data and behavior into objects to help manage the size and complexity of larger programs, as programs become more cluttered with many disorganized functions without classes and objects.
2. Constructing and using objects in PHP involves creating an object instance with the new keyword, accessing object fields and methods, and defining classes with fields, constructors, and methods.
3. Classes in PHP can extend other classes to inherit their data and behavior, and can define static methods, fields, and constants to be shared across instances rather than replicated in each object. Abstract classes and interfaces enable polymorphism.
Declarative Data Modeling in Python
This document introduces valid_model, a Python library for declarative data modeling. It allows defining data models using descriptors to specify data types and validation rules. This provides strict typing while remaining unopinionated about persistence. Custom descriptors can extend the library's functionality. The library aims to enable use cases like database modeling, form validation, and API request/response objects.
Pyconie 2012
This document summarizes lessons learned from building MongoDB and MongoEngine. Some key lessons include: dive in and start contributing to open source projects to help them progress; metclasses are an important tool that allow ORM functionality to be added to classes; not all new ideas are good and it's important to avoid straying too far from existing patterns that users expect; tracking changes at a granular level allows partial updates but adds complexity. Overall it encourages contributors to learn why certain approaches were taken and focus on improving existing designs rather than introducing radical changes.

Slick: Bringing Scala’s Powerful Features to Your Database Access
This talk will teach you how to use Slick in practice, based on our experience at EatingWell Media Group. Slick is a totally different (and better!) relational database mapping tool that brings Scala’s powerful features to your database interactions, namely: static-checking, compile-time safety, and compositionality.
Here at EatingWell, we have learned quite a bit about Slick over the past two years as we transitioned from a PHP website to Scala. I will share with you tips and tricks we have learned, as well as everything you need to get started using Slick in your Scala application.
I will begin with Slick fundamentals: how to get started making your connection, the types of databases it can access, how to actually create table objects and make queries to and from them. We will using these fundamentals to demonstrate the powerful features inherited from the Scala language itself: static-checking, compile-time safety, and compositionality. And throughout I will share plenty of tips that will help you in everything from getting started to connection pooling options and configuration for use at scale.
