Find the size of Image in Python

def jpeg_res(filename):
""""This function prints the resolution of the jpeg image file passed into it"""
# open image for reading in binary mode
with open(filename,'rb') as img_file:
# height of image (in 2 bytes) is at 164th position
img_file.seek(163)
# read the 2 bytes
a = img_file.read(2)
# calculate height
height = (a[0] << 8) + a[1]
# next 2 bytes is width
a = img_file.read(2)
# calculate width
width = (a[0] << 8) + a[1]
print("The resolution of the image is",width,"x",height)
jpeg_res("img1.jpg")


Output:
The resolution of the image is 280 x 280
