A have a fairly large text file that I need to reorder the lines such as….
line1 line2 line3
Reordered to look like this
line2 line1 line3
File will continue with more lines and the same reordering must occur. I’m stuck and need a loop to do this. Unfortunately, I have hit a speed bump.
with open('poop.txt') as fin, open('clean330.txt', 'w') as fout: for line in fin: ordering = [1, 0, 2] for idx in ordering: # Write output lines in the desired order. fout.write(line)
