Load data from txt with pandas

I am loading a txt file containig a mix of float and string data. I want to store them in an array where I can access each element. Now I am just doing

import pandas as pd

data = pd.read_csv('output_list.txt', header = None)
print data

This is the structure of the input file:
1 0 2000.0 70.2836942112 1347.28369421 /file_address.txt

Now the data are imported as a unique column. How can I divide it, so to store different elements separately (so I can call
)? And how can I define a header?

You can use:

data = pd.read_csv('output_list.txt', sep=" ", header = None)
data.columns = ["a", "b", "c", "etc."]

Add sep=" " in your code and leave a blank space between the quotes. So pandas can detect spaces beetween values and sort in columns. Data columns is for naming your columns.
