Usage of sys.stdout.flush() method
...ider the following simple Python script:
import time
import sys
for i in range(5):
print(i),
#sys.stdout.flush()
time.sleep(1)
This is designed to print one number every second for five seconds, but if you run it as it is now (depending on your default system buffering) you may not s...
How do I design a class in Python?
...g.footstep(0)
Now, it may be that for your case you need to read in your raw data file and compute the footstep locations. All this could be hidden in the footstep() function so that it only happens once. Something like:
class Dog:
def __init__(self):
self._footsteps=None
def footste...
convert double to int
...etc - although you'll still need a cast afterwards.
Don't forget that the range of int is much smaller than the range of double. A cast from double to int won't throw an exception if the value is outside the range of int in an unchecked context, whereas a call to Convert.ToInt32(double) will. The r...

How would I mix patterns and numeric ranges in sed (or any similar tool - awk for example)? What I want to do is match certain lines in a file, and delete the next n lines before proceeding, and I want to do that as part of a pipeline.

C++ Erase vector element by value rather than by position? [duplicate]
... It moves all values not equal to the value passed to the beginning of the range [begin,end). With your example in the question you'd get 5,9,2,0,7,7. As remove() however returns an iterator to the new end, vec.erase() can remove the obsolete elements (i.e. the second 7 here) if that is needed.

Is gettimeofday() guaranteed to be of microsecond resolution?
...ure (I'm still trying to get the patch in) there will be a CLOCK_MONOTONIC_RAW that will not be modified at all, and will have a linear correlation with the hardware counters." I don't think the _RAW clock ever made it into the kernel (unless it was renamed _HR, but my research suggests that effort...
Return empty cell from formula in Excel
...'re going to have to use VBA, then. You'll iterate over the cells in your range, test the condition, and delete the contents if they match.
Something like:
For Each cell in SomeRange
If (cell.value = SomeTest) Then cell.ClearContents
Next

Are list-comprehensions and functional functions faster than “for loops”?
...ode-level loop:

9 STORE_FAST 1 (x)
