Hi,
I was writing a module for the black-scholes pricing model in python, but I
keep getting this error message:
Traceback (most recent call last): File "", line 1, in File
"C:\Python26\lib\blackscholes.py", line 25d2=d1-v*sqrt(t)
This is the code in my blackscholes.py file:#Black
I noticed some odd behavior relating to eval(). First, a baseline case for
behavior:
>>> def test():
... x = 5
... return [a for a in range(10) if a == x]
...
>>> test()
[5]
So far so good. Now let's try eval:
>>> c = compile('[a for a in range(10) if a == x]', '', 'single')
>>> eval(c, globals(
Hi Steven,
Thanks a BUNCH for helping me! Yes, you were correct in assuming that my input
data are already names. They're names in a column in a csv file. They're the
names of GPs, in various formats. Besides the forms I've mentioned already
there
are examples such as 'Doctor's office Duh, J.

No.
Python string literals use backslash escapes for special characters,
similar to what many other computer languages, including C, do.

There's a few things I've noticed:
1. I would recommend using an IDE of some sort. I copy and pasted this into
eclipse, and it told me straight away that you had a parenthesis problem on
this line: d1=(log(s/x)+((r+v**2/2)*t)/(v*sqrt(t))
2. Your function "dividend" isn't returning a value.
3. Un
