Format Date time in AngularJS
...a date. You can force it using new Date, but that is a bit of a pain on an array. Since you can pipe filters together, you might be able to use a filter to convert your input to a date and then apply the date: filter on the converted date. Create a new custom filter as follows:
app
.filter("asDate"...

Why do we need tuples in Python (or any immutable data type)?
.... It so happens that in many people's typical use cases, lists tend to be array-like and tuples tend to be record-like. But this shouldn't stop people from using lists for heterogeneous data if it suits their problem better. As the Zen of Python says: Practicality beats purity.

Awaiting multiple Tasks with different results
...esult, z.Result);
}
but this does lots of overhead and allocates various arrays (including the params Task[] array) and lists (internally). It works, but it isn't great IMO. In many ways it is simpler to use an async operation and just await each in turn:
async Task<string> DoTheThings() {

What do (lambda) function closures capture?
...do this would be to use a function that takes two parameters instead of an array:
add = lambda a, b: a + b
add(1, 3)
However, using lambda here is a bit silly. Python gives us the operator module, which provides a functional interface to the basic operators. The lambda above has unnecessary overh...
How to select rows from a DataFrame based on column values?
...lues to identify which rows to keep. Typically, we'd name this series, an array of truth values, mask. We'll do so here as well.
mask = df['A'] == 'foo'
We can then use this mask to slice or index the data frame
df[mask]
A B C D

2 foo two 2 4
4 foo ...
Logger slf4j advantages of formatting with {} instead of string concatenation
...cient) log-level check or the (slimmer, but perhaps minor overhead) object array parameter. (I'd prefer the latter, all things being equal.) It's hard to say that the string concat's won't be important/won't impact performance. The object array creation could in theory be inlined and optimized away ...
