Dear all,
I read in Python in a Nutshell that when we have multiple assignments
made on a single line, it is equivalent to have those many simple
assignments and that the right side is evaluated once for each
assignment. [The wordings are mine. I am not sure if this is what he
Hi,
Is there any gain in performance because of augmented assignments.
x += 1 vs x = x+1
Or are both of them the same.

In python all numbers are immutable. This means there is one object ( a
region in the memory ) created every time we do an numeric operation. I
hope there should have been some good reasons why it was designed this way.
But why not have mutable numbers also in the

Given a string
s = 'a=1,b=2'
I want to create a dictionary {'a': '1', 'b': '2'}
I did,
dict(map(lambda k: k.split('='), s.split(',')))
Is it possible to get rid of the lambda here, without having to define
another function just for this.
Is this the easiest/straight-forward way to do this?
I got it:
dict([k.split('=') for k in s.split(',')])

I have a list of sets in variable lsets .
Now I want to find the intersection of all the sets.
r = lsets[0]
for s in r[0:]:
r = r s
Is there any other shorter way?
Thanks in advance,

Hi,
a = '/home/suresh/doc/html/a1/'
b = '/home/suresh/doc/'
I am looking for a standard function which will return the location of b
relative to a i.e. '../..'
I have gone through the os and os.path modules, but could not find any
function of use. Should I write my own?
Exactly what I wanted.
It would be nice if the standard float function takes care of these.
regards,
Suresh
how about:
SI_prefixes = {
'Y':24, 'Z':21, 'E':18, 'P':15, 'T':12, 'G':9, 'M':6, 'k':3,
'h':2, 'd':-1, 'c':-2, 'm':-3, u'\xb5':-6, 'u':-6, 'n':-9, 'p':-12,
'f':-15,
Hi,
I want to convert a string to float value. The string contains
engineering symbols.
For example,
s = '12k'
I want some function which would return 12000
function(s)
= 12000.0
I searched the web, but could not
Hi,
I have a string like,
s1 = '12e3'
s2 = 'junk'
Now before converting these values to float, I want to check if they
are valid numbers.
s1.isdigit returns False.
Is there any other function which would return True for s1 and False
for s2.
Hi all,
Lets say I have an array:
from numarray import *
a = array([ 6, 7, 8, 9, 10, 11, 12])
I want to multiply out all the elements and get the result.
r = 1.0
for i in a:
r = r*i
Is there any faster, efficient
