Welcome to Pygritia’s documentation!¶
Pygritia is a symbolic expression library.
It can
- create symbolic expressions with one or more symbols
- resolve symbolic expressions by substituting values to symbols
- partially resolve symbolic expression
Example:
from pygritia import symbol, evaluate, update
this = symbol('this')
that = symbol('that')
arr = [1, 2, 3]
print(5 / this + 2 * 6) # 5 / this + 12
print(evaluate(5 / this + 2 * 6, this=2)) # 14.5
print(evaluate(this[that], this=arr)) # [1, 2, 3][that]
update(this[that], 42, this=arr, that=1)
print(arr) # [1, 42, 3]
Documentation of all public functions can be found in pygritia.
