I have a text file containing such data ;

But I only need Section B, and I need to change the notation to ;
8.000e-02 = 0.08
0.000e+00 = 0.00
4.000e-02 = 0.04
Does it have to be python? If not, I'd go with something similar to
sed 1,2d foo.data | awk '{printf("%.2f\n", $2);}'
Why sed and awk:
awk 'NR>2 {printf("%.2f\n", $2);}' data.txt
And in Python:
f = open("data.txt")
f.readline() # skip header
f.readline() # skip header
for line in f:
print "%02s" % float(line.split()[1])
