loops - python: append to end of first line in a text file -

-

i have loop ending in

statsg.append(str(mean))

and after loop

np.savetxt(path+'stats.txt',statsg,'%s')

so after 2 iterations text file 2 lines of text in stats.txt file. i'd prefer have 1 line of text (i.e. second iteration of loop appends end of first iterations output.

your question not clear, can initiate empty string before loop, in each iteration append it. 

string_to_save = '' line in file:     string_to_save += line save_function(file_name, string_to_save)

if not helpful edit question more details asked in comments.
