I don't know of one. This code requires a radial coordinate.
class Pt(object):
def __init__(self, x=0.0, y=0.0, z=0.0):
self.x = x
self.y = y
self.z = z

The readlines() file method returns a list. The read() method returns a string. A str object has no insert() method but a list object does.

Changefilestring = f.read() tofilestring = f.readlines()

Here is one way to do it:
>>> class test(object):
... def change_var(self, name, value):
... globals()[name] = value
...
>>> var = 123
>>> obj = test()
>>> obj.change_var('var', 456)...

If you want to determine if a number is prime or not, you should return True (if prime) or False (if not prime). Use the modulo operator to determine if the entered number is divisible by loop...

I like using list comprehensions for this kind of task.
>>> cols = 4
>>> rows = 5
>>> array = [[0 for i in range(cols)] for j in range(rows)]
>>> array
[[0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0],...

It depends on the type of data and how you intend to use it.
>>> adam = "john"
>>> adam += "mike"
>>> adam
'johnmike'
>>> ' '.join([adam, 'fred'])
'johnmike fred'
>>>

If I understand you correctly, you want to substitute the "VALUE" of a residence feature which would be a "KEY" in a dictionary. For each different value, there will be a different key. A dictionary...

I guess the rotate method does not return the rotated object. Try this:for n,r in enumerate([90,180,270]):
im1.rotate(r).crop(box) # ? im1 = im1.rotate(r).crop(box)
im1.save("screen%s.jpg"...

#2 I am not sure, but methods crop() and rotate() should return image objects. If so, you could simply:for n in range(1, 4):
im1 = im1.rotate(90).crop(box)
im1.save("screen%s.jpg" % n)

Sometimes it's easier to show some code:
import time, datetime

data = '2008-10-27 12:05:54'
fmt = '%Y-%m-%d %H:%M:%S'

ts1 = time.strptime(data, fmt)

dt1 =...

You must close the file object to flush the output buffers. You can manually flush the buffers with file method flush().

random.sample() may be what you are looking for.
>>> let = [ 'a', 'b', 'c', 'd', 'e', 'f', 'g' ]
>>> random.sample(let,len(let))
['a', 'd', 'g', 'b', 'c', 'f', 'e']
>>> random.sample(let,3)...

Andy,

No forgiveness necessary. Doing exercises like this is a good way to learn. That's one reason I am doing it.

I posted to a similar thread recently, but I can't remember where. The following will preserve punctuation:from string import punctuation as stuff

def words_between(s, first, second):

I played around with a function that returns a list of factors a few months ago. You only need to check numbers up to sqrt(number).def factors(num):
outList = [i for i in xrange(1,...

Not to be picky, but an iterable can be converted to a list with the built-in function list.
>>> import string
>>> list(string.letters)
['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l',...

Use string method strip() to remove newline characters.
for line in lines:
filemenu.add_cascade(label=line.strip())

You can use escape sequence \b to match exact words.
import re

s = "I'm trying to debug a problem but the debugger is not working"

target = 'debug'
repl = 'fix'

patt = re.compile(r'\b%s\b'...

Since I am using Python 2.3, I will define a function to pass to sort().
def comp(a,b):
return cmp(a[5], b[5])

f = open('sample_data.txt')
data_list = [[float(item) for item in...

File method readline() reads an entire line from an open file at the file's current position. The file position is relocated. File method tell() returns the current position. Example:>>> f =...

You don't need regex for this:
>>> array = ['red','blue']
>>> array1 = [' %s ' % item for item in array]
>>> array1
[' red ', ' blue ']

By adding a __cmp__ method to class Movie, you can sort instance objects in list m1 with list method sort(). Following is an example of a __cmp__ overload in a Vector class that sorts on the x, y and...

You can use string formatting for your regex pattern. The following iterates on the file object. For the top 10 players, variable data should have 40 items. Match object m.groups() should have 5...

You are returning a tuple in cun_to_centimeters(). Access the elements of the tuple by slicing.
Example:
>>> def ret_tuple():
... return 1, 2
...
>>> obj = ret_tuple()
>>> obj[0]
1
>>>...

>>> s = 'XXXXX -\n\t XXXX'
>>> ''.join(s.split())
'XXXXX-XXXX'
>>>

Here is an example using woooee's suggestion:
s = '''ABCD vvvv 1e-12
ABCD hhhh 1e-6
ABCD ggggg 1e-3
ASDE ffffff 1e-57
ASDE dddd 0.001'''

dd = {}
for item in s.split('\n'):
itemList =...

ich1,

A class that inherits from object is called a "new-style" class. "Old-style" or "classic" classes are likely to be deprecated some time in the future.

Inheritance! Your new class object fruitcake will inherit the attributes of object. See this snippet: http://www.daniweb.com/code/snippet354.html

Close the log file, then open again for reading.log_file.close()
log_file = open('%s' % os.path.join(logfile_path, file))
lineList = log_file.readlines()
log_file.close()

Example using the timeit module:

def my_function():
return results

if __name__ == '__main__':
import timeit
t = timeit.Timer("my_function()", "from __main__ import my_function")...

Try this:
csv.reader(str(self[filename]).split('\n')The argument to csv.reader can be any iterable object that produces a string each time its next() method is called.

self[filename] does not appear to be a valid file name. Following is an example of a valid file name:
r'H:\Zip_Files\618 Johnston\IFA040308\24747-IFA040308.zip'

The csv module is ideal for your parsing your data.
import csv

fn = 'data.csv'
f = open(fn)
reader = csv.reader(f)
headerList = reader.next()
outputList = []
for line in reader:
# test...

's.template' contains the original string passed to Template().
s.substitute() returns a string object which can be assigned to a variable.

If I understand you correctly, there are several ways:

# Update the local namespace
