Python: Initialize a variable into if [duplicate]

Question

Is there a way to do this in python?:

def exist(path_image):
    if path.isfile(path_image):
       return path_image
    else:
       return False

path_image = '/home/user/image.jpg'
if (image = exist(path_image)):
   print(image)

Other languages like PHP and Javascript, I can initialize a variable inside 'IF'

Thanks

you could make it a side effect of a function call. tho, it's not good idea. — ShpielMeister

No, Python on purpose makes assignment not an expression. A PEP was created proposing this, and it was never accepted: python.org/dev/peps/pep-0379 — juanpa.arrivillaga

No, you cannot do this in Python. A simple alternative would be:

image = exist('/home/user/image.jpg')
if (image):
   print(image)
