It would be nice.
Looks like str(1+3j) is returning an expression in string
form. Maybe there is no actual complex literal.
eval (str(1+3j)) works.
Python 2.4.2 (#1, Jan 23 2006, 21:24:54) [GCC 3.3.4] on linux2
Type
py> c = complex(1, 3)
py> print c
(1+3j)
py> d = complex('1+3j')
py> print d
(1+3j)
py> str(1+3j)
'(1+3j)'
complex takes two numbers, or a string representing a complex number.
the string you supply isn't a representation of valid complex number.

Says who?
By normal conventions in Python, "str" attempts only to make a "nice"
human readable representation. The function "repr" is usually expected
to provide output that can be parsed back into the original o
I am not exactly sure what is going on, but I get the error:
ValueError: complex() arg is a malformed string
I think that it might be because the value of 'j' is not defined.
But I am a newbie so I could very well be wrong.
