Looks like the data to be written is buffered, so actual write takes
place after readlines(), when close() flushes buffers.
See io package documentation, BufferedIOBase.
The solution is file.flush() after file.write()
Can't deny, such a behaviour looks utterly weird. Try to avoid designing
Hi all,
what do you see looking at format string syntax
https://docs.python.org/3/library/string.html#formatstrings ?
In particular, at something like this:

Yes, this is syntactically correct statement and if we tweak Formatter
methods, we can generate

It's a simple template system based on standard string formatting. You
declare your template strings as class attributes and they are formatted
in the right order. For

This idea has a couple of flaws so can be regarded as bad.

you could (and maybe you do) write in your functions
