Specifying Dependencies
In Poetry, dependencies are specified in the pyproject.toml
file, a standard configuration file for Python projects. Dependencies can be listed under the [tool.poetry.dependencies]
section for main dependencies and [tool.poetry.dev-dependencies]
for development dependencies.
Basic Dependency Specification
A basic dependency specification includes just the package name and optionally the version:
[tool.poetry.dependencies]
requests = "^2.25.1"
In this example, the requests
library is specified with a version constraint. Let’s delve into the various ways to specify versions, ranges, and constraints.
Understanding Versions, Ranges, and Constraints in Python Poetry
Managing dependencies is a fundamental aspect of maintaining a Python project. Poetry, a powerful dependency management tool, simplifies this process by providing a clear and concise way to declare, manage, and resolve dependencies. Here we check how to specify dependencies in Poetry, adding, removing, updating dependencies, and the use of versions, ranges, and constraints.
