Sorry Python but it is what it is.

Would that just create a list of the current packages/versions

Yes, and all downstream dependencies

without actually locking anything?

What do you mean? Nothing stops someone from manually installing an npm package that differs from package-lock.json - this behaves the same. If you pip install -r requirements.txt it installs the exact versions specified by the package maintainer, just like npm install the only difference is python requires you to specify the “lock file” instead of implicitly reading one from the CWD

As I understand, when you update npm packages, if a package/version is specified in package-lock.json, it will not get updated past that version. But running those pip commands you mentioned is only going to affect what version gets installed initially. From what I can tell, nothing about those commands is stopping pip from eventually updating a package past what you had specified in the requirements.txt that you installed from.

I don’t follow. If my package-lock.json specifies package X v1.1 nothing stops me from manually telling npm to install package X v1.2, it will just update my package.json and package-lock.json afterwards

If a requirements.txt specifies X==1.1, pip will install v1.1, not 1.2 or a newer version. If I THEN install package Y that depends on X>1.1, the pip install output will say 1.1 is not compatible and that it is being upgraded to 1.2 to satisfy package Y’s requirements. If package Y works fine on v1.1 and does not require the upgrade, it will leave package X at the version you had previously installed.
