Question

I am very new to Python so please forgive the following basic code and problem, but I have been trying to figure out what is causing the error I am getting (I have even look

Answer 1

Even though @Ignacio gave you a straightforward solution, I thought I might add an answer that gives you some more details about the issues with your code...

# You are not saving this result into a variable to reuse
os.path.join(src_dir, f)
# Should be
src_path = os.path.join(src_dir, f)

# you open the file but you dont again use a variable to reference
with open(f)
# should be
with open(src_path) as fh

# this is actually just looping over each character 
# in each result of your os.listdir
for line in f
# you should loop over lines in the open file handle
for line in fh

# write? Is this a method you wrote because its not a python builtin function
write(line)
# write to the file
fh.write(line)
