Dear Support Team,
I have built a function (enclosed here) to merge many files (in this
example is 2 files: "a1.txt" and "a2.txt") lines by lines. The output
file is called "final_file". However, i could not have it run
successfully.
Content of "a1.txt":
1
3
5
Content of "a2.txt":
2
4
6
Content of "final_file.txt" will be like:
1
2
3
4
5
6
In Python, i called just written module:
import argument
reload(argument)
argument.test(2,"C:/a1.txt","C:/a2.txt")
and get the error as below:
"ValueError: I/O operation on closed file
File "c:\append.py", line 5, in <module>
argument.test(2,"C:/a1.txt","C:/a2.txt")
File "c:\argument.py", line 28, in test
for line_data in f:"
Could you please advise the resolution for this?
What does " I/O operation on closed file" suggest to you?
