how to print/write the result to a file

[Li Chen]

Hi folks,

Assume I have an array=[1,2,3]

How do I print/write the result to a file called test.text either in the
same folder or in a different folder?

Thanks in advance,

Li

It depends on the format you want, e.g.

File.open('path/to/test.txt', 'w') do |f|
f.write(array.join(', '))
end

1. you can use forward slashes (/) even on windows
2. instead of f.write you could use f.puts, f.print, etc.
3. another version is:

f = File.open(',...', 'w')
f.puts ...
f.close

The block version is safer than this as it closes the file
automatically, even in the case of exception within the block.
