The following code will gove you
a plot of the shape of the curve.
from matplotlib import pyplot as plt
import numpy as np
f = np.zeros(40)
v = np.arange(0,4,0.1)
for i in np.ara
First fill the first row and first column of the matrix with seperate loops.
Then the rest of the elements of the matrix can be filled with nested loops.

In python we have a set of imread and imshow in skimage. In matplotlib.image
we again have imreadand imshow functions. In scipy.misc we again have
another set imread and imshow. Are there anyfunctional differences between
these multiple sets to justify their presence? …

This is an aliasing problem. Change the code to
super = []
sub = [""]*3
other = ["a","b","c","d"]
sub[0] = "hi"
sub[1] = "hello"
for item in other:
l = sub[:]
l[2] = item
super.append(l)
for item in super:
print item

Change your code to

# +++your code here+++
ls=[]
ls1=[]
for str in words:
if str[0]=='x':
ls.append(str)
else:
ls1.append(str);
print ls
print ls1
ls = sorted(ls)
ls1 = sorted(ls1)
ls.extend(ls1)
return ls

A lot of confusion is caused by the print function converting an integer or
float
to a string before printing to console. thus both '1234 and '1234' are
shown as
1234 on the console. Similarly '15.4' and 15.4 are displayed as 15.4. There
is no way
to tell which is a string, which is an int and whic

Then Isaac's function does that(but you have to leave a space after
last number in the string).
def foo(x):
a, b = 0, ""
for i in x:
if i != " ":
b += i
else:
print ("this is b", b)
a += int(b)
print ("this is a",a)

You can call the function as
string_sum("10 4 5 ")
Output will be 19.

The following code should do.
for a in range(1,10):
for b in range(1,5):
for c in range(1,5):
for mc in range(50, 55):
if mc ==(6*a)+(9*b)+(20*c):
print "mc= ",mc,"a= ",a,"b= ",b,"c=",c

winsound.Beep() takes only integral values for frequency.
Therefore you cannot use it if you want either just intonation or
equal temperment scales exactly.

As far as programming volume is concerned winsound.Beep has only frequency
and duration.

One can ofcourse increase the volume by adjusting master volume.
But one needs ability to program volume level in order to produce
sounds of different volume levels in a piece of music.

My OS is Windows XP. I have Python 2.7.3(32 bit). My question is
are there any commands in Python which directly allow me to produce a pure
note
of a given frequency, given volume and given duration. Further can we access
the different sound channels(sound card) available through Python.
