Graph Algorithm To Find All Connections Between Two Arbitrary Vertices
...raph in parallel, should you for some reason wish to do that.
Here's some test code demonstrating how the function given above works:
# test graph:

How do Trigonometric functions work?
...uncated to the ±1 domain because any value outside it is meaningless.
To test the approximating functions, a billion random function evaluations were forced to be evaluated (that is, the -O3 optimizing compiler was not allowed to bypass evaluating something because some computed result would not b...
When should one use a spinlock instead of mutex?
...e it a try and compare the results (e.g. using a profiler), but be sure to test both cases, a single-core and a multi-core system before you jump to conclusions (and possibly different operating systems, if your code will be cross-platform).

How is __eq__ handled in Python and in what order?
...that was looked for, but it was deprecated and removed in Python 3.)
Let's test the first check's behavior for ourselves by letting B subclass A, which shows that the accepted answer is wrong on this count:
class A:
value = 3
def __eq__(self, other):
print('A __eq__ called')

Change one value based on another value in pandas
...lowing code might be helpful for you.
import pandas
df = pandas.read_csv("test.csv")
df.loc[df.ID == 103, 'FirstName'] = "Matt"
df.loc[df.ID == 103, 'LastName'] = "Jones"
As mentioned in the comments, you can also do the assignment to both columns in one shot:
df.loc[df.ID == 103, ['FirstName', ...
