I wrote like this.
str = "curl -s 'URL_ADDRESS' | tail -1".split()
p = subprocess.Popen(str,stdout=subprocess.PIPE).stdout
data = p.read()
p.close()
print(data)
But the result is b''.
What's the problem with this?

If you use subprocess, use instead of '|' like this.
This will solve the problem.
str = "curl -s 'URL_ADDRESS'".split()
tail = "tail -1".split()
temp = subprocess.Popen(str, stdout=subprocess.PIPE).stdout
temp1 = subprocess.Popen(tail, stdin=temp, stdout=subprocess.PIPE).stdout
temp.close()
data = temp1.read()
temp1.close()
