How to change the type of a variable in python?

Question

Python

Good afternoon,
Sending bash spript output data to zabbix server.
Bash script counts the number of lines in a file (wc -l).
The variable turns out to be a string variable, and zabbix treats it as text.
And I need the variable to be numeric in order to plot graphs on zabbix.
Python 2.7.7, how to change variable type to numeric output?
### Bash script run
p = subprocess.Popen("./test", stdout=subprocess.PIPE, shell=True)
(output, err) = p.communicate()
p_status = p.wait()
print "Command output : ", output
print "Command exit status/return code : ", p_status
subprocess.call(['/usr/bin/zabbix_sender', '-z', 'x/x/x/x', '-p', '10051', '

Answer 1

your_int_variable = int(your_str_variable)

Answer 2

str(int(output)) - for some reason only this helped.
