Which is faster : if (bool) or if(int)?
...ngs like sign-extend to bring it to certain widths to put it on the stack, etc. (You can't push a byte.)
When the optimizer views the AST and does its magic, however, it looks at surrounding context and "knows" when it can replace code with something more efficient without changing semantics. So ...
What's the “big idea” behind compojure routes?
...responsibility to examine the URI used in the request, examine any cookies etc. and ultimately arrive at an appropriate response. Clearly it is necessary that all this work be factored into a collection of well-defined pieces; these are normally a "base" handler function and a collection of middlew...
How do I check what version of Python is running my script?
... 5)
This compares major and minor version information. Add micro (=0, 1, etc) and even releaselevel (='alpha','final', etc) to the tuple as you like. Note however, that it is almost always better to "duck" check if a certain feature is there, and if not, workaround (or bail out). Sometimes feature...
Reading a binary file with python
...all, or you will read the wrong bits.
Reading the contents of the file in order to have something to unpack is pretty trivial:
import struct
data = open("from_fortran.bin", "rb").read()
(eight, N) = struct.unpack("@II", data)
This unpacks the first two fields, assuming they start at the very b...

Cast to int vs floor
...will run into some overflow issues) and for negative values below -100000, etc. But I've clocked it to be at least 3 times faster than floor, which was really critical for our application. Take it with a grain of salt, test it on your system, etc. but it's worth considering IMHO.

Get the subdomain from a URL
...cause each TLD differs on what counts as a subdomain, second level domain, etc.
Keep in mind that there are top level domains, second level domains, and subdomains. Technically speaking, everything except the TLD is a subdomain.
In the domain.com.uk example, "domain" is a subdomain, "com" is a se...
Deleting lines from one file which are in another file
...print }' exclude-these.txt from-this.txt
The output will be in the same order as the "from-this.txt" file. The tolower() function makes it case-insensitive, if you need that.
The algorithmic complexity will probably be O(n) (exclude-these.txt size) + O(n) (from-this.txt size)
