biogeme.expressions.convert.expression_to_value(expression, betas=None)

Convert to float, if possible :type expression: Expression | float | int | bool :param expression: expression to be converted :rtype: float :return: numerical value

Parameters:

• expression (Expression | float | int | bool)

• betas (dict[str, float] | None)

Return type:

float

biogeme.expressions.convert.get_dict_expressions(the_dict)

If the dictionary contains float, they are transformed into a numerical expression.

Return type:

dict[int, Expression]

Parameters:

the_dict (dict[int, Expression | float | int | bool])

biogeme.expressions.convert.get_dict_values(the_dict, betas=None)

If the dictionary contains Expressions, they are transformed into a numerical expression.

Return type:

dict[int, float]

Parameters:

• the_dict (dict[int, Expression | float | int | bool])

• betas (dict[str, float] | None)

biogeme.expressions.convert.validate_and_convert(expression)

Validates the expression and returns the converted expression if necessary.

Return type:

Expression

Parameters:

expression (Expression | float | int | bool)
