Question

How can I write to a global file inside of a function?

Example:

output_file=open("output_file_name.txt", "w")

def write_to_file:    
    global output_file    
    output_file.write('something')

write_to_file()

output_file.close()

The code above is not working. It says “ValueError: I/O operation on closed file”
Any ideas?

Answer 1

write_to_file is a function,

try

def write_to_file():

othrwise the code is fine
