binfix | Java Bytecode Deobfuscation | Bytecode library

Let me start by saying that I know nothing about Python, but I am trying to learn(mostly through struggling it seems). I've looked around this site and tried to cobble together code to do what I need it to, but I keep running into problems. Firstly, I need to convert a file of 2 columns and 512 rows of strings to floats then put them in a 512x2 array. I check the first column (all rows) for negative values. If negative, add 512. Then I need to reorder the rows in numerical order and write/save the new array.

On to my first problem, converting to floats and putting the floats into an array. I have this code, which I made from others' questions:

with open("binfixtest.composite") as f: f_values = map(lambda l: l.strip().split(' '), f) print f_values newarray = [map(float, v) for v in f_values]

Original format of file:

-91. 0.444253325 -90. 0.883581936 -89. -0.0912338793

New format of f_values: ['-91. 0.444253325'], ['-90. 0.883581936'], ['-89. -0.0912338793']

I'm getting the error:

Traceback (most recent call last): File "./binfix.py", line 10, in newarray = [map(float, v) for v in f_values] ValueError: invalid literal for float(): -91. 0.444253325

which I can't seem to fix. If I don't convert to float, when I try to add 512.0 to negative rows it gives me the error TypeError: cannot concatenate 'str' and 'float' objects

Any help is most definitely appreciated as I am completely clueless here.
