A little utility to take the pain out of writing vendor prefixed CSS3 animations

css_animation_util.py

a   = [ 'webkit', 'moz', 'ms', 'o', '' ]
n   = 'enter'

f   = {
    'from'  : [
        'opacity: 0',
        '.transform( e(\'rotate(360deg)\')'
    ],
    'to'    : [
        'opacity: 1',
        '.transform( e(\'rotate(0deg)\')'
    ]
}

for p in a:
    print '@' + ( '-' + p + '-' if p else '' ) + 'keyframes ' + n
    print '{'
    
    for k, v in f.items():
        print "\t" + k + ( '%' if k.isdigit() else '' ) + ' { ' + '; '.join( v ) + ' }'
    
    print '}'
