Applying "%.1f" to multiple variables

Question

Just started a course and the exercise was to learn how to use round(x, n) to truncate floats.

Only problem is, it didn't. I found out about how to use %.1f online, but is there a way to apply it to multiple variables instead having to write it over and over?

I have it set up like below:

a = float(input("a:"))
b = float(input("b:"))
c = float(input("c:"))
d = float(input("d:"))
e = float(input("e:"))

sum = a + b + c + d + e
average = sum/5

print ("The sum of ", "%.1f" % (a), ", ", "%.1f" % (b), ",", "%.1f" % (c), ", ", "%.1f" % (d), ", and ", "%.1f" % (e), "is ", "%.1f" % (sum), ". Meanwhile, the average is ", "%.2f" % (average), ".")

Is there a way to apply the %.1f without having to write it so much?

edit: thanks to everyone that helped out. I found onur güngör's to have worked best with what I'm looking for, but I learned a lot more than what I needed from everyone's input. appreciate it.

I guess you want something like this.

n = 10
vars = []
for i = range(1, n+1):
  vars.append(float(input("%d: " % i)))

vars_sum = sum(vars)
average = vars_sum/5

str = "The sum of "
for var in vars[:-1]:
  str += "%.1f, " % var
str += "and " + "%.1f" % vars[-1:][0] + " is %.1f." % vars_sum
str += " Meanwhile, the average is %.2f." % average
print(str)
