By usingfilter(field1__field2=value)you can filter based on subelements further down in a parsed token. >>>sentence.filter(feats__Degree="Pos")TokenList<quick,brown,lazy> Filters can also be chained (meaning you can dosentence.filter(...).filter(...)), and filtering on multiple propert...
In this case, if the file doesn’t exist, we instantly return meaning we have nothing to process. As for the second example with ATMs: def print_atm_statistics(atms: List[AtmMachine]) -> None: if not len(atms): return basic_atm = atms[0] print_atms_in_city(basic_atm.city) ...

The choice of interatomic interaction model not only controls the cost for each evaluation, but also the physical or chemical meaning of the results. Typically, relatively fast potentials are used, but these often have two issues. One is that they make incorrect predictions for low-energy structur...
In caseconditionAequalsfalse, then the output should bethingC. This utilizes a combination of boolean logic. if (A) { if (B) {} } Combining the two conditions using AND has the same meaning. if (A && B) () On the other hand, when expressions are nested, comprehending them becomes ...

In one-to-one coupling (a), the dimensions and their meaning are preserved. Contraction coupling (c) reduces the dimensionality by summing over one or more dimensions. Expansion coupling (d, e) increases the dimensionality by providing input that is constant along the extra dimensions (''ridge...
