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}') 1Use: .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)) Or: f-string formatting from Python 3.6:
print(f'Total score for {name} is {score}') Can use repr and automatically the '' is added:
print("Total score for" + repr(name) + " is " + repr(score)) # or for advanced: print(f'Total score for {name!r} is {score!r}') 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)) Just follow this
grade = "the biggest idiot" year = 22 print("I have been {} for {} years.".format(grade, year)) OR
grade = "the biggest idiot" year = 22 print("I have been %s for %s years." % (grade, year)) And forget all others, else the brain won't be able to map all the formats.
1Just try:
print("Total score for", name, "is", score) Use f-string:
print(f'Total score for {name} is {score}') Or
Use .format:
print("Total score for {} is {}".format(name, score)) 2print("Total score for %s is %s " % (name, score)) %s can be replace by %d or %f
If score is a number, then
print("Total score for %s is %d" % (name, score)) If score is a string, then
print("Total score for %s is %s" % (name, score)) If score is a number, then it's %d, if it's a string, then it's %s, if score is a float, then it's %f
This is what I do:
print("Total score for " + name + " is " + score) Remember to put a space after for and before and after is.
The easiest way is as follows
print(f"Total score for {name} is {score}") Just put an "f" in front.
This was probably a casting issue. Casting syntax happens when you try to combine two different types of variables. Since we cannot convert a string to an integer or float always, we have to convert our integers into a string. This is how you do it.: str(x). To convert to a integer, it's: int(x), and a float is float(x). Our code will be:
print('Total score for ' + str(name) + ' is ' + str(score)) Also! Run this snippet to see a table of how to convert different types of variables!
