Off topic:Looping over a section of data and suming in python

Question

[elhamidihay]

I have a fairly large dataset, I would like to read data from a file and sum values equal to 1 for every row and write it to a file. My code just prints data back to me

Example input file:

1526  0 1 2 1 0

782   0 1 1 1 2

7653  1 1 1 0 0

87bt  1 0 1 2 2

Example desired output file:

1526 2

782 3

7653 3

87bt 2

my code:

df = pd.read_csv("data1", header=None, index_col=0) 

df.eq(1).sum(axis=1)
