Printing in Scheme works by calling display (and possibly, newline). Since you want to call it sequentially before/after something else (which, in a functional (or in the case of Scheme, functional-ish) language only makes sense for the called functions side-effects), you would normally need to use begin, which evaluates its arguments in turn and then returns the value of … Read more
Although you need a pair of parentheses to print in Python 3, you no longer need a space after print, because it’s a function. So that’s only a single extra character. If you still find typing a single pair of parentheses to be “unnecessarily time-consuming,” you can do p = print and save a few characters that way. … Read more
In Python 2.x print is actually a special statement and not a function*. This is also why it can’t be used like: lambda x: print x Note that (expr) does not create a Tuple (it results in expr), but , does. This likely results in the confusion between print (x) and print (x, y) in Python 2.7 However, since print is a special syntax statement/grammar construct in Python 2.x then, without … Read more
There are many ways to do this. To fix your current code using %-formatting, you need to pass in a tuple: Pass it as a tuple:print(“Total score for %s is %s” % (name, score)) A tuple with a single element looks like (‘this’,). Here are some other common ways of doing it: Pass it as a dictionary:print(“Total … Read more
By printing multiple values separated by a comma: The print statement will output each expression separated by spaces, followed by a newline. If you need more complex formatting, use the ”.format() method: or by using the older and semi-deprecated % string formatting operator.
You can use the print statement to do this without importing sys. The comma on the end of the print line prevents print from issuing a new line (you should note that there will be an extra space at the end of the output). The Python 3 SolutionSince the above does not work in Python 3, you can do this instead (again, … Read more
I found this to be the only one short, flexible, portable and readable: The function eprint can be used in the same way as the standard print function:

Alright, I know how to print variables and strings. But how can I print something like “My string” card.price (it is my variable). I mean, here is my code: print “I have ” (and here I would like to print my variable card.price).
