redpoint 1.4.1

Climbing grade converter

🔴 redpoint

Converting climbing grades made easy!

🔴 redpoint is a Python library that simplifies climbing grade conversions. It supports a wide range of climbing grade systems (sport, bouldering, and more) from thecrag.com, allowing users to easily convert between systems (e.g., YDS to French), compare the difficulty of grades, and even generate ranges of equivalent grades.

Overview

Converting the grades between the systems:

from redpoint import Grade

Grade("5.12a", "YDS").to("French")  # <7a+, 'French'>

when typing Grade gets tedious, individual systems can be imported as well:

from grading.systems import YDS

YDS("5.12a").to("French")  # <7a+, 'French'>

Comparing the difficulty of grades:

Grade("5.14a", "YDS") > Grade("8a", "French")  # True
Grade("V11", "V-Scale") == Grade("8A", "Fontainebleau")  # True
UIAA("4") >= Ewbanks("33")  # False

Getting the range of the grade in different system:

Brittish("5a").to_range("French")  # [<5b, 'French'>, <5b+, 'French'>, <5c, 'French'>, <5c+, 'French'>, <6a, 'French'>]

For the full list of features check out the documentation.
