Python Packages

Common packages such as SciPy and NumPy are available across all Python modules. Other commonly used packages are listed below:

Python Package Import Command Description Available in
Biopython import Bio Collection of Python tools for computational biology and bioinformatics, containing classes to represent biological sequences and sequence annotations, and it is able to read and write to a variety of file formats. Also allows for a programmatic means of accessing online databases of biological information, such as those at NCBI. Separate modules extend Biopython's capabilities to sequence alignment, protein structure, population genetics, phylogenetics, sequence motifs, and machine learning. python/anaconda/4.0/2.7 python/anaconda/4.0/3.5
IPython import IPython Enhanced interactive shell for Python, including tools for parallel computing python/anaconda/4.0/2.7 python/anaconda/4.0/3.5 python/anaconda/4.1.1/2.7
