Select the true statements about the sqlite3 module. (Select two answers.)

AThe fetchalt method returns None when no rows are available

BThe execute method allows you to perform several queries at once

CThe execute method is provided by the Cursor class

DThe fetchone method returns None when no rows are available

Show Suggested Answer

Suggested Answer: A, D

ConfigParser is a built-in library in Python that allows you to read and write configuration files. The read method is used to read the configuration file which can be in any of the supported file formats, such as INI, YAML, and JSON. The read_dict method is used to read the configuration from a Python dictionary. The read_conf and read_str options are not valid methods in the ConfigParser module.

Therefore, the correct options to load a configuration using ConfigParser are A. read and D. read_string.

You can’t perform multiple queries with execute, just one at a time!

Nope, fetchalt isn't a method in sqlite3.

I feel like the execute method is definitely part of the Cursor class, but I can't recall if it allows multiple queries.

I remember practicing a question about the execute method, and I think it can only run one query at a time.

Okay, I think I've got a good strategy here. I'll start by identifying the true statements, which are the ones that match the module's actual functionality. Then I'll double-check any that I'm not 100% sure about.

The fetchalt method? I don't think that's a real method in the sqlite3 module. I'll focus on the more common methods like fetchone and fetchall.

Hmm, I'm a bit unsure about the execute method allowing you to perform several queries at once. I'll have to double-check that one.

I'm pretty confident about this one. The execute method is definitely provided by the Cursor class, and the fetchone method returns None when no rows are available.

I'm a little unsure about the "suppression data set" as well. That doesn't seem directly related to getting Einstein Vision up and running. I'd focus more on the model, permissions, and baseline data.

Date is definitely one of the choices, and I think Text might be another one. But I'm not confident about the third option.

Hmm, I think I've seen questions like this before. If “y” is selected, it might mean the switch has to reboot for the new code to take effect?

Okay, I've got this. The first step is to determine the correct inventory valuation at the end of each period. Then I need to identify any price variances that should be recorded. I feel confident I can work through this systematically.

The sqlite3 module is like a good friend - it's always there for you, but you never know quite what to expect. I'm sticking with C) and D) and hoping the module doesn't pull any fast ones on me.

This is a tricky one, but I'm going with C) and D) as well. The sqlite3 module can be a bit finicky, but at least we don't have to worry about the fetchalt method, which sounds like something the developers made up just to mess with us.

Oh man, I was totally going to pick B) about executing multiple queries at once. That would be so convenient, but I guess it's not true for the sqlite3 module. At least I know C) and D) are correct now.

I'm pretty sure the correct answers are C) and D). The execute method is definitely from the Cursor class, and the fetchone method returns None when there are no more rows to fetch.
