input variable into python call subprocess

I have a small python snippet that calls a larger program (I did not write the larger one).

call(['function1', file1,  file2,  'data.labels=abc, xyz'])

The above works.

input ='abc, xyz'

Now I want to input "abc, xyz" as a variable holding this value

call(['function1', file1,  file2,  'data.labels=input'])

but it does not work.

How can I pass a variable value into variable data.labels within call subprocess.

call(['function1', file1,  file2,  'data.labels=' + input)

If for some reason, input is not a string.

call(['function1', file1,  file2,  'data.labels=' + str(input) )

Another way to do the same:

call(['function1', file1,  file2,  'data.labels={0}'.format(input)])
