I am attempting to figure out the python code for a specific process. If any of the lines in file1 are not in file2 I want to append the contents of file2 to file3. I attempted a nested for loop and am just writing test data to make sure the iterations are working properly. I am only receiving the same number of lines as int text2.txt and I expected it to have responses the number of line in text2 times the number of lines in text1.
file1=open(text1.txt, 'r+')
file2=open(text2.txt, 'r+')
file3=open(text3.txt, 'a+')
for line1 in file1:
for line2 in file2:
if line1==line2:
file3.write("same" + 'rn')
else:
file3.write("different" + 'rn')
Example
file1
Tom
Harry
file2
Harry
Tom
Lilly
Print nothing in file3.
File1 is the same as above
File2
Harry
Lilly
David
File3 should read *I understand my code doesn't read this way today.
Harry
Lilly
David
File3 reads today
different
different
different
File3 what I expected
different
different
different
same
different
different
Please explain how I get to my ultimate goal and what did I do wrong?
