[Python] How to run yamllint command line using Python?

I want to run yamllint(yaml_file) using subprocess module in Python. I know there is another module to call yamllint in Python, but I want to do it using subprocess.

lint='yamllint("%s")'%(args.yaml)
print(lint)

p=subprocess.Popen(lint,shell=True,stdout=subprocess.PIPE,stderr=subprocess.PIPE)
stdoutdata,stderr=p.communicate()
if stderr:
print(stderr)
print("Please check YAML format")
quit()


This gives me an error:

b'/bin/sh: -c: line 0: syntax error near unexpected token `"delete.yaml"\'\n/bin/sh: -c: line 0: `yamllint("delete.yaml")\'\n'


Please help me understand what is wrong in this.
