Dear Group,
I got a question which might be possible but I am not getting how to
do it.
If I have a list, named,
list1=[1.0,2.3,4.4,5.5]
Now each element in the array holds the string property if I want to
convert them to float, how would I do it?
Extracting the values with for and
did you try type casting with float ?

I'm guessing you have something like
list1=['1.0', '2.3', '4.4', '5.5', ...], right?
You can do this:
for i in range(len(list1)):
list1[i] = float(list1[i])
There's almost certainly a 1-liner you can use, but this should work.

If you want to have it even shorter and you are using Python 2.5 or
greater you can also use:
list1 = [float(list_item) for list_item in list1]

for i, x in enumerate(list1):
list1[i] = float(x)

But you must be sure that the list only contains objects than can be
converted into float, if not you'll get:
float('something')
Traceback (most recent call last):
File pyshell#0, line 1, in module
float('something')
ValueError: could not convert string to float: something

That looks like a list of floats already. Perhaps you meant:
list1 = [1.0, 2.3, 4.4, 5.5]

Better,
list1 = [float(v) for v in list1]
One statement only - long
Thanks Bruno. I just missed it. I got it back and thanks Blockhead for
giving me new angle to look into the problem.
Best Regards,
Subhabrata.
Nothing personal, but it's Blockheads (plural) AND you missed the OI OI.
What is the problem with modern day education? :)
