Print multiple arguments in Python
Print multiple arguments in Python
Question
This is just a snippet of my code:
print("Total score for %s is %s ", name, score)
But I want it to print out:
"Total score for (name) is (score)"
where name is a variable in a list and score is an integer. This is Python 3.3 if that helps at all.

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 score for %(n)s is %(s)s" % {'n': name, 's': score})
There's also new-style string formatting, which might be a little easier to read:
Use new-style string formatting:
print("Total score for {} is {}".format(name, score))Use new-style string formatting with numbers (useful for reordering or printing the same one multiple times):
print("Total score for {0} is {1}".format(name, score))Use new-style string formatting with explicit names:
print("Total score for {n} is {s}".format(n=name, s=score))Concatenate strings:
print("Total score for " + str(name) + " is " + str(score))
The clearest two, in my opinion:
Just pass the values as parameters:
print("Total score for", name, "is", score)If you don't want spaces to be inserted automatically by
printin the above example, change thesepparameter:print("Total score for ", name, " is ", score, sep='')If you're using Python 2, won't be able to use the last two because
printisn't a function in Python 2. You can, however, import this behavior from__future__:from __future__ import print_functionUse the new
f-string formatting in Python 3.6:print(f'Total score for {name} is {score}')

There are many ways to print that.
Let's have a look with another example.
a = 10
b = 20
c = a + b
#Normal string concatenation
print("sum of", a , "and" , b , "is" , c)
#convert variable into str
print("sum of " + str(a) + " and " + str(b) + " is " + str(c))
# if you want to print in tuple way
print("Sum of %s and %s is %s: " %(a,b,c))
#New style string formatting
print("sum of {} and {} is {}".format(a,b,c))
#in case you want to use repr()
print("sum of " + repr(a) + " and " + repr(b) + " is " + repr(c))
EDIT :
#New f-string formatting from Python 3.6:
print(f'Sum of {a} and {b} is {c}')
Use: .format():
print("Total score for {0} is {1}".format(name, score))
Or:
// Recommended, more readable code
print("Total score for {n} is {s}".format(n=name, s=score))
Or:
print("Total score for" + name + " is " + score)
Or:
`print("Total score for %s is %d" % (name, score))`
In Python 3.6, f-string is much cleaner.
In earlier version:
print("Total score for %s is %s. " % (name, score))
In Python 3.6:
print(f'Total score for {name} is {score}.')
will do.
It is more efficient and elegant.
Keeping it simple, I personally like string concatenation:
print("Total score for " + name + " is " + score)
It works with both Python 2.7 an 3.X.
NOTE: If score is an int, then, you should convert it to str:
print("Total score for " + name + " is " + str(score))
