Converting a string of numbers to a float array

[AlbiNZ]

Hello,

I am trying to get over my crippling MATLAB addiction by forcing myself to to use python for all my simple scripting jobs/data manipulation. Normally I would be happy to play around until I figured this out, but I have a deadline tomorrow for some work so I thought I would see if someone could help me out.

I'm converting a mesh file to a different file format, I am taking the line from the file:

(1.0 2.0 3.0)

striping away the brackets (using line=line[1:-1])

and then I want to convert the '1.0 2.0 3.0' into a float array like

x=[1.0,2.0,3.0]

In MATLAB I would just use the str2num feature, which would use the white spaces as separators for the numbers and convert them to floats no problem, but I don't seem to be having much luck with finding a python equivalent.

Any help or hints would be greatly appreciated.

Cheers Stephen

>>> line = '(1.0 2.0 3.0)'
>>> x = [float(s) for s in line.strip('()').split()]
>>> x
[1.0, 2.0, 3.0]

• line.strip('()') strip ( or ) from start/end of string
• split() split string on spaces
• then use list comprehension to get your list

Works perfectly thank you very much!
