Reading numbers from file and normalizing

Hello Everyone, I want to load the data I have in a file, which looks like:


Now, I want to load this from the file and compute the normalization. I do:

f = open("Input.txt", "r") 
data = [line.strip() for line in f]
print data
norm = [float(i)/sum(data) for i in data]
print norm

But, I am getting the error:

ValueError: invalid literal for float()

Although, I do the process directly into python 2.7 console in linux like,

a = [21.4,0.266667,0,0.966667,0.166667,0.966667,0.533333,0.1]
norm = [float(i)/sum(a) for i in a]
print norm

This works fine. I don't know what I am doing wrong. Please help me and I am new to programming. Thanks in advance!
