Public repository of the Cosmic Linear Anisotropy Solving System (master for the most recent version of the standard code; GW_CLASS to include Cosmic Gravitational Wave Background anisotropies; classnet branch for acceleration with neutral networks; ExoCLASS branch for exotic energy injection; class_matter branch for FFTlog)
I'm new in the code CLASS and I try run some notebooks, specifically the notebook thermo.ipynb, when I run the cell 3 returns the error:
File "", line 23
print thermo.viewkeys()

SyntaxError: invalid syntax
