python pyyaml 3.12版本模块给出了意外的输出

我正在尝试从yaml文件生成值并替换。但是YAML3.12版本给了我错误的格式。我无法下载最新版本的pyyaml。这是公司限制。因此，我只想获得yaml 3.12版本的预期输出。请帮忙

代码如下：

import yaml
print (yaml.__version__)
import sys

file_name = sys.argv[1]

variables = open(file_name)
variables_list = yaml.load(variables, Loader=yaml.Loader)
#print(variables_list)

values = open('values.yaml')
values_list = yaml.load(values, Loader=yaml.Loader)
#print(values_list)

for k,v in values_list.items():
    #print (k,v)
    if values_list[k] == None:
        try : values_list [k] = variables_list[k]
        except  KeyError  : pass
    
print (yaml.dump(values_list))

输出：

 /usr/local/bin/python3 /Users/mbhamidipati/Downloads/yamlscript.py kong_hydra_refresh_dev1_westus2_cp5_azure.yaml
