I'm not sure such a thing exists but Python is generally an easy language to learn. Python documentation is generally very clear and easy to follow. From the Python interpreter you can also use the dir() and help() methods to view methods, attributes and documentation which makes it easy to explore what options are available to you in Python.
A few examples of differences between PHP and Python:
Python:
x = [1, 2, 3, 4, 5]
for a in x:
print a
print "Loop is over"
PHP:
$x = array(1, 2, 3, 4, 5);
foreach($x as $a) {
echo $a.PHP_EOL
}
echo 'Loop is over'.PHP_EOL;
As you can see, Python does away with using '{' and '}' and instead uses indentation to see when the for-loop is complete.
Python:
x = {'spam':'hello', 'eggs':'world'}
if x.get('spam'):
print x['spam']
PHP:
$x = array('hello'=>'spam', 'world'=>'eggs');
if array_key_exists('hello', $x) {
echo $x['hello'].PHP_EOL;
}
