Biopython (Python3) ​

  • Biopython represents an ecosystem of related biology tools written in the Python3 programming language

  • Unlike with BioJulia, Biopython tools are installed together as modules into a single biopython package

  • Launched over two decades ago with major releases covering the Python2/3 transition

  • Capabilities cover a number of molecular biology applications including sequence alignment, population genetics, and machine learning

A few similar applications between BioJulia and Biopython:

ApplicationBioJulia packagesBiopython objects/modules
Sequence annotationGenomicFeatures, GenomicAnnotationsSeq, SeqRecord
Input/OutputFASTX, XAM, BigWig, etc.Bio.SeqIO, Bio.AlignIO
Sequence alignmentBioSequences, BioAlignmentsBio.Align
Population geneticsPopGenBio.PopGen

A few notable differences between Julia and Python3:

JuliaPython3
High-level, general-purpose compiled languageHigh-level, general-purpose interpreted language
Expression-based (statements yield a value)Statement-based (statements don't always yield a value)
Dynamically typed with multiple dispatch and optional type annotationsDynamically typed with optional type annotations
Built-in parallelism via threads, coroutines (Tasks)Limited (GIL) built-in parallelism via threads, async/await
Lisp-like (homoiconic, macro-based) metaprogrammingReflection-based runtime metaprogramming
Included default package managerNo default package manager (poetry, conda, and other alternatives available)
Single implementation available (JuliaLang)Multiple implementations available (PyPy, Numba, etc.)
Arrays are column-major (columns are contiguous in memory)(Numpy) arrays are row-major by default (rows are contiguous in memory)
