Is there an easier way without having to call the str() method?

Author Name Status Posted Time Shirly Selkirk 3/24/2008 10:02:37 PM Author is Offline Hi friends, After getting raw_input from the user, I want to print a sentence that ends in an integer and then the "." character. Of course, if I print using a comma (,) I don't get an error but there is an ugly space between the integer and the period. But if I try "+" then I obviously get a str/int concatenation error. One way to solve this is to convert the int into a str and then "+" works. But is there an easier way without having to call the str() method?

Post Comments Re: Python Shirly Selkirk 3/25/2008 12:25:41 AM Python. So here is some code... num = raw_input("Pick a number: ") num = int(num) print "Your number times 5 is", num * 5, "." This produces a space between num and the period. If I try to use "+" I get an error trying to concatenate a str and int. It's possible to print str(num) and then concatenate that result with the period to eliminate the space. But I was wondering if there was a more obvious way than calling the str() function.

Code: ( python ) num = int(raw_input("Pick a number: ")) print "Your number times 5 is " + str(num * 5) + "." I guess it's a matter of preference, but that's h ow I do all my string/int concatenations... Post Comments Re: Is there an easier way without having to call the str() method?

My favorite way (because there are several) is using string formatting. Code: ( text ) >>> num = raw_input("Pick a number: ") >>> num = int(num) >>> print "Your number times 5 is %d."%(num * 5) Your number times 5 is 30. You could also move the int() call to tighten the code a little. Code: ( text ) >>> num = int(raw_input("Pick a number: ")) >>> print "Your number times 5 is %d."%(num * 5) Your number times 5 is 40. or for that matter Code: ( text ) print "Your number times 5 is %d."%(int(raw_input("Pick a number: ")) * 5) Onc e you start worrying about what happens if the user enters a non numeric value like "a&quo t; you will want to explore the try: and except: block.

String formating with %s uses str() to generate the string. Code: ( python ) num = int(raw_input("Pick a number: ")) print "Your number times 5 is %s." % (num * 5) Post Comments Re: Thanks everybody!
