New submission from Stéphane Blondon <[email protected]>:
The documentation is not explicit about the behaviour if several files are read
by the same ConfigParser: the data are not reset between two read().
I suggest to add such information in the documentation. There is a draft:
=== start ===
When a `ConfigParser` instance make several calls of `read_file()`,
`read_string()` or `read_dict()` functions, the previous data will be overriden
by the new ones. Otherwise, the previous data is kept. This behaviour is
equivalent to a `read()` call with several files passed to `filenames`
parameter`.
Example:
config = configparser.ConfigParser()
s = """
[spam]
alpha=1
"""
config.read_string(s)
# dict(config["spam"]) == {'alpha': '1'}
config.read_string("")
# dict(config["spam"]) == {'alpha': '1'}
=== end ===
What do you think about it?
I can do a PR but I wonder where is the best location in the documentation to
insert it.
At the end of the 'Quick start paragraph'
(https://docs.python.org/3/library/configparser.html#quick-start)? Or perhaps a
new paragraph after 'Fallback Values'? Other location?
