In practice, what are the main uses for the new “yield from” syntax in Python 3.3?
...n g:
yield v
wrap = reader_wrapper(reader())
for i in wrap:
print(i)
# Result
<< 0
<< 1
<< 2
<< 3
Instead of manually iterating over reader(), we can just yield from it.
def reader_wrapper(g):
yield from g
That works, and we eliminated one line of code....

How to split a file into equal parts, without breaking individual lines? [duplicate]
I was wondering if it was possible to split a file into equal parts ( edit: = all equal except for the last), without breaking the line? Using the split command in Unix, lines may be broken in half. Is there a way to, say, split up a file in 5 equal parts, but have it still only consist of whole li...

Measuring text height to be drawn on Canvas ( Android )
...way to measure the height of text?
The way I am doing it now is by using Paint's measureText() to get the width, then by trial and error finding a value to get an approximate height. I've also been messing around with FontMetrics , but all these seem like approximate methods that suck.

Understanding FFT output
...tputs because you are using a complex to complex FFT. Remember that you've converted your 32 samples into 64 values (or 32 complex values) by extending it with zero imaginary parts. This results in a symetric FFT output where the frequency result occurs twice. Once ready to use in the outputs 0 to N...
