I know this is probably an easy one but I am still new to Python and need a little push in the right direction. I have a text file that I need a certain number of spaces where on character 88 an N is placed going on to the new line. The test file I am using looks like this:

aaaa aaaaa

What my desired output (for testing) would look like this:

aaaa N aaaaa N

With my coding I am getting

aaaa N aaaaa N

I have tried to manually code it (no if statements) but get the output above:

`newf=””
with open(‘testfile.txt’,’r’) as f:
for line in f:

    newf+=line.strip()+"      Nn"
f.close()

with open(‘testfile.txt’,’w’) as f:
f.write(newf)
f.close()`

I have tried an in-statement but keep getting errors

spacef = "" newf="" with open('testfile.txt','r') as f: for line in f: if newf <= 88: newf+=line.strip()+" " f.close() with open('testfile.txt','w') as f: f.write(newf) f.close()

IndentationError: expected an indented block after ‘if’ statement on line 5

Any help would be appreciated

adding if statement
