 # encoding: utf-8

Password="dTwCrjHosJn2", 
Version="2015-12-15", "
) 
The config={
'conversion_target' : 'NORMALIZED_TEXT', 
# Use a custom configuration. 
'PDF' : {
'heading' : {
'fonts: [
{" level ": 1, 'min_size: 24}, 
{' level: 2, 'min_size: 16,' max_size: 23, 'bold' : True}, 
{' level: 2, 'min_size: 14,' max_size: 17, 'italic: False} 
] 
} 
} 
}
