What does the constant 0.0039215689 represent?
...ication by 0.0039215689f converts an integer valued color intensity in the range 0 to 255 to a real valued color intensity in the range 0 to 1.

How would I extract a single file (or changes to a file) from a git stash?
...(see git rev-parse manpage for explanation of rev^! syntax, in "Specifying ranges" section).
Likewise, you can use git checkout to check a single file out of the stash:
$ git checkout stash@{0} -- <filename>
or to save it under another filename:
$ git show stash@{0}:<full filename> ...
Unicode characters in URLs
... Domain names have nothing to do with this. All browsers disallow a wide range of characters to prevent phishing. Displaying non-ASCII characters in the path or query string part does not create a similar vilnerability. IE simply didn't bother to implement it. (And Firefox is the only one that imp...
How do I plot in real-time in a while loop using matplotlib?
...y as np
import matplotlib.pyplot as plt
plt.axis([0, 10, 0, 1])
for i in range(10):
y = np.random.random()
plt.scatter(i, y)
plt.pause(0.05)
plt.show()
Note some of the changes:
Call plt.pause(0.05) to both draw the new data and it runs the GUI's event loop (allowing for mouse in...
How to append multiple values to a list in Python
...
>>> lst
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
>>> lst.extend(range(11, 14))
>>> lst
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]
So you can use list.append() to append a single value, and list.extend() to append multiple values.
