如何使用python将yaml块转换为json块？

我有一个生成yaml数据的脚本。我需要它来生成等效的json数据

代码如下：

def main(argv):
        global top
        global version
        global package
        librivox_rest_url       = 'unknown'
        app_image_url           = 'unknown'
        password                = 'XXXXXXX'
        try:
              opts, args = getopt.getopt(argv,"hl:t:v:k:p:i:",["url=","top=","version=","package=","password=","image_url="])
        except getopt.GetoptError:
              print 'make_hiera_data_from_librivox_api.py -l <librvox url> [-t <top>] [-v <version>] [-p <password>]'
              sys.exit(2)
        for opt, arg in opts:
                if opt == '-h':
                        usage ( 'Help called' )
                        sys.exit(0)
                elif opt in ("-l", "--url"):
                        librivox_rest_url = arg
                elif opt in ("-t", "--top"):
                        top = arg
                elif opt in ("-v", "--version"):
                        version = arg
                elif opt in ("-p", "--password"):
                        password = arg
                elif opt in ("-k", "--package"):
