pyextremes is a Python library aimed at performing univariate Extreme Value Analysis (EVA). It provides tools necessary to perform a wide range of tasks required to perform EVA, such as:

• extraction of extreme events from time series using methods such as Block Maxima (BM) or Peaks Over Threshold (POT)
• fitting continuous distributions, such as GEVD, GPD, or user-specified continous distributions to the extracted extreme events
• visualization of model inputs, results, and goodness-of-fit statistics
• estimation of extreme events of given probability or return period (e.g. 100-year event) and of corresponding confidence intervals
• tools assisting with model selection and tuning, such as selection of block size in BM and threshold in POT

I wanted to give kudos to Jean Toilliez who has inspired me to develop this open-source project and who taught me a lot about the extreme value theory. Also big thanks to Max Larson who has introduced me to software development and statistics.
