I have some issue putting variable into the path

Question

it 's possible to put a variable into the path in python/linux

for example :

>>>counter = 0;

>>>image = ClImage(file_obj=open('/home/user/image'counter'.jpeg', 'rb'))

I have syntax error when i do that.

The [documentation](https://docs.python.org/3/library/string.html#format-string-syntax) might be helpful here — DavidG, Nov 12 '18 at 09:59

You could use an f-string if you’re working in python 3.6+

This is the most efficient method.

counter = 0
filepath = f"/home/user/image{counter}.jpeg"
image = ClImage(file_obj=open(filepath, 'rb'))

Otherwise the second best would be using the .format() function:

counter = 0
filepath = "/home/user/image{0}.jpeg".format(counter)
image = ClImage(file_obj=open(filepath, 'rb'))

You can use Python's .format() method:

counter = 0
filepath = '/home/user/image{0}.jpeg'.format(counter)
image = ClImage(file_obj=open(filepath, 'rb'))

>>>counter = 0;

>>>image = ClImage(file_obj=open('/home/user/image' + str(counter) + '.jpeg', 'rb'))
