Perhaps, but while the PHP community will debate endlessly about standards and projects inevitably end up become a pile of inconsisten spaghetti code, the conventions in Python make uniformity the path of least resistance, at least by an order of magnitude.

Also, while Rails is in the same league as Django as far as tools and expressiveness go(expressiveness perhaps more so), Django goes to considerable lengths to enforce style and consistency; it is not taboo to politely tell people that their code is not PEP8 compliant.

While certainly not as strict as PEP8, the Ruby community also has accepted style conventions that all bigger projects follow (especially Rails) and that you can call out people on.
