print out the pattern in an array in python

Question

I have a list which contains 3 machines in python which is ARRAY_MACHINE= ['machine1', 'machine2', 'machine3']

And, I want to write a script that can access 2 or 3 items at a same time in that list (depend on the array). If the ARRAY_MACHINE has 3 items like above, it will print out

The machines are machine1, machine2, machine3

If the ARRAY_MACHINE has 2 items, it will print out.

The machines are machine1, machine2

How can I do that? So far, I used while loop to do that, and it can only loop through each item in that list.

print "The machines are" , ', '.join(ARRAY_MACHINE)

This will do the job nicely.

Join function will join the elements of an array with the delimiter specified.

Use join:

Python 3:

>>> ARRAY_MACHINE= ['machine1', 'machine2', 'machine3']
>>> print('The machines are {}'.format(', '.join(ARRAY_MACHINE)))
The machines are machine1, machine2, machine3

>>> ARRAY_MACHINE= ['machine1', 'machine2']
>>> print('The machines are {}'.format(', '.join(ARRAY_MACHINE)))
The machines are machine1, machine2

Python 2:

>>> ARRAY_MACHINE= ['machine1', 'machine2', 'machine3']
>>> print 'The machines are {}'.format(', '.join(ARRAY_MACHINE))
The machines are machine1, machine2, machine3

>>> ARRAY_MACHINE= ['machine1', 'machine2']
>>> print 'The machines are {}'.format(', '.join(ARRAY_MACHINE))
The machines are machine1, machine2

Wow, that's awesome. That's print statement suppose to be a command on Linux. And, I was struggle a lot using bash script to do it (since, they are terrible in loop). Thank you a lot :)

@Alexander If you are using python2, print is a statement..in python3 (As i have used) its a function..

I will replace that print statement by a command in Linux. And, I will check the version if Python in my company later

Try this

import sys
ARRAY_MACHINE= ['machine1', 'machine2', 'machine3']

for i, data in enumerate(ARRAY_MACHINE):
    if(i == 0 ):
        sys.stdout.write ("The machines are ")
    sys.stdout.write (data+" ")
