Unpythonic way of printing variables in Python?

The only other way would be to use the Python 2.6+/3.x .format() method for string formatting:

# dict must be passed by reference to .format()
print("{foo}, {bar}, {baz}").format(**locals()) 

Or referencing specific variables by name:

# Python 2.6
print("{0}, {1}, {2}").format(foo, bar, baz) 

# Python 2.7/3.1+
print("{}, {}, {}").format(foo, bar, baz)    

Using % locals() or .format(**locals()) is not always a good idea. As example, it could be a possible security risk if the string is pulled from a localization database or could contain user input, and it mixes program logic and translation, as you will have to take care of the strings used in the program.

A good workaround is to limit the strings available. As example, I have a program that keeps some informations about a file. All data entities have a dictionary like this one:

myfile.info = {'name': "My Verbose File Name", 
               'source': "My Verbose File Source" }

Then, when the files are processes, I can do something like this:

for current_file in files:
    print 'Processing "{name}" (from: {source}) ...'.format(**currentfile.info)
    # ...

I prefer the .format() method myself, but you can always do:

age = 99
name = "bobby"
print name, "is", age, "years old"

Produces: bobby is 99 years old. Notice the implicit spaces.

Or, you can get real nasty:

def p(*args):
    print "".join(str(x) for x in args))

p(name, " is ", age, " years old")
