Basically, strings are immutable. If you need to append something to a
string, you need to construct a new string object with th
Beside casting it with str(), you can also use a format string:
assert "%d" % 10 == "10"
assert "%5d" % 10 == " 10"
assert "%05d" % 10 == "00010"
In practice % supports a superset of what printf in C provides.

Well, there are basically two ways to go at it.
If you want it at module level, you need to generate the functions:
sensor = {'sens1': 200, 'sens2': 300}
for key in sensor.keys():
def helper(keytofetch=key):
return sensor[keytofetch]
globals()[key] = helper
print sens1()

Basically as you can see above, @X before a function definition takes

That is almost the same as using ordinary dict access, with slightly
different syntax, e.g. senso
import re
num = 12345678
print ','.join(re.findall("\d{3}", str(num)))
output:
123,456
Where is the '78'?
It looks like that solution inserts comma's from left to right
instead of from right to left.

The problem with that is that it cuts the digits in the end of the
number, if they can't form a 3 digit value.
Example:
import re
n = 1234
print ",".join

Django uses this function:

there is no pattern in the numbers. but don't worry about it, because all i
am doing is this:
two strings that look like "2.3.3.3.3.", youknow, str(int) + "." +
str(int) + "." and so forth
are presented and they equal to a value, which is the third string.
in short, given the first two strings

You want to "pop up" a console window? Usually if your program is
running in a console you have a window already. Use raw_input() to get
user input in the console.

Another part of program takes care of that patternless stuff, only saving
and retrieving for comparison is concerned for this part of the code.
In [11]: d = { ('a', 'b'): '1',
: ('c', 'd'): '2' }
In [12]:
In [12]: d['a', 'b']
Out[12]: '1'
that does look like what I looking for, how does

Hello,

"module" is very specific, it is a single Python source file. A library
is a collection of useful modules.
