Very close! In your select expression, you have to use a pipe (|) before contains. This filter produces the expected output. . – map(select(.Names[] | contains (“data”))) | .[] .Id The jq Cookbook has an example of the syntax. Filter objects based on the contents of a key E.g., I only want objects whose genre … Read more
You can use negative lookaheads: ^(?!.*\.\.).*$ That causes the expression to not match if it can find a sequence of two periods anywhere in the string.
It is just two ! boolean not operators sitting next to each other. The reason to use this idiom is to make sure that you receive a 1 or a 0. Actually it returns an empty string which numifys to 0. It’s usually only used in numeric, or boolean context though. You will often see … Read more
You can use exclude() in place of filter(): Entry.objects.exclude(name__contains=”SomeString”) (“give me all entries EXCEPT those with names containing “SomeString”) And when dealing with Q object you can use “~” symbol before Q object to represent negation. For example the following statement means “give me all Entries with names containing “Elephant”, but NOT containing “SomeString”: Entry.objects.filter(Q(name__contains=”Elephant”) … Read more
Just use not. isinstance just returns a bool, which you can not like any other.
The “conditional abs” you propose is not equivalent to std::abs (or fabs) for floating point numbers, see e.g. #include <iostream> #include <cmath> int main () { double d = -0.0; double a = d < 0 ? -d : d; std::cout << d << ‘ ‘ << a << ‘ ‘ << std::abs(d); } output: … Read more
Just negate the filter: MyModel.query.filter(sqlalchemy.not_(Mymodel.name.contains(‘a_string’)))
You can use a not (!) operator… but you have to use Spring 3.2 M1. The following syntax is now supported <beans profile=”A,!B”> @Profile({“A”, “!B”}) indicating that the element or annotated component should be processed only if profile ‘A’ is active or profile ‘B’ is not active. See change announced here: Spring Framework 3.2 M1 … Read more
short answer: YES Ref: http://docs.scipy.org/doc/numpy/reference/generated/numpy.invert.html Notice: Computes the bit-wise NOT of the underlying binary representation of the integers in the input arrays. This ufunc implements the C/Python operator ~. and bitwise_not is an alias for invert: >> np.bitwise_not is np.invert >> True
