# According to pypa/pipenv#598, it is recommended to include Pipfile.lock in version control. | ||
# However, in case of collaboration, if having platform-specific dependencies or dependencies | ||

# install all needed dependencies. | ||
#Pipfile.lock | ||
|
||
# poetry | ||
# Similar to Pipfile.lock, it is generally recommended to include poetry.lock in version control. | ||
# This is especially recommended for binary packages to ensure reproducibility, and is more | ||
# commonly ignored for libraries. | ||

# Similar to Pipfile.lock, it is generally recommended to include pdm.lock in version control. | ||
