pow() function returns float or integer?

Today, someone posted this code and asked why x is float ? 
>>> from math import pow
>>> x = pow(5, 2)
>>> x
25.0
It's float because the pow function of math package returns float. But there is a built-in pow function in Python which will return integer in this case. You need to restart the python interpreter before you run the following code : 
>>> a = 5
>>> x = pow(a, 2)
>>> x
25
>>> type(x)
<type 'int'>
So, don't get confused. Happy coding! :)

This is my code but why returns float??

It returns float because you are using the pow function from math package.

He is confused Because In your code you also used the 'pow' function but your return type is integer!

>>> a = 5
>>> x = pow(a, 2)
>>> x
25
>>> type(x)

OK, added this line in my post : "You need to restart the python interpreter before you run the following 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
