How to get image size from url

Today I needed to get image size (width and height) from image urls. I am sharing my python code here.

import requests
from PIL import Image
from io import BytesIO


def get_image_size(url):
    data = requests.get(url).content
    im = Image.open(BytesIO(data))    
    return im.size


if __name__ == "__main__":
    url = "http://4.bp.blogspot.com/_A2NamGQmyCc/TO1nWedGQQI/AAAAAAAAAnA/WxBVyEGHxjc/s1600/sbn_pic_2.jpg"
    width, height = get_image_size(url)
    print width, height

I used pillow - which is a PIL fork.

Feel free to comment if you have any suggestion to improve my code.

Strip HTML tags using Python

We often need to strip HTML tags from string (or HTML source). I usually do it using a simple regular expression in Python. Here is my function to strip HTML tags: def remove_html_tags(data): p = re.compile(r'<.*?>') return p.sub('', data) Here is another function to remove more than one consecutive white spaces: def remove_extra_spaces(data): p = re.compile(r'\s+') return p.sub(' ', data) Note that re module needs to be imported in order to use regular expression. Here you can find an updated code that gets the text from html: http://love-python.blogspot.com/2011/04/html-to-text-in-python.html

lambda magic to find prime numbers

Find prime number up to 100 with just 3 lines of code. The 4th line is for printing ;) nums = range(2, 100) for i in range(2, 10):     nums = filter(lambda x: x == i or x % i, nums) print nums Isn't it amazing? Check my new post about Prime number: http://love-python.blogspot.com/2010/11/prime-number-generator-in-python-using.html

Convert text to ASCII and ASCII to text - Python code

Python has a very simple way to convert text to ASCII and ASCII to text. To find the ASCII value of a character use the ord() function. Example: >>> ord('B') 66 To get a character from it's ASCII value use the chr() function. Example: >>> chr(65) 'A' Here is a program to get the list of all characters along with their values: # program to print the list of characters and their ASCII values for value in range(0, 255): print "ASCII Value:", value, "\t", "Character:", chr(value), "\n" Here is another simple ASCII encoding-decoding program: # Convertion from text to ASCII codes message = raw_input("Enter message to encode: ") print "Decoded string (in ASCII):" for ch in message: print ord(ch), print "\n\n" # Convertion from ASCII codes to text message = raw_input("Enter ASCII codes: ") decodedMessage = "" for item in message.split(): decodedMessage += chr
