 for i in range(10):
  principal = principal * (1 + apr)
  print "The value in 10 years is:", principal

print-loopの外に行を移動するだけforです:

for i in range(10):
    principal = principal * (1 + apr)
print "The value in 10 years is:", principal

    principal = input("Enter the initial principle: ")
    apr = input("Enter the annual interest rate: ")
    for i in range(10):

        print "The value in {0} years is: {1}".format(i + 1, principal)

本当に 10 年の値だけに関心がある場合は、for ループを次のように置き換えます。

print "The value in 10 years is:", principal * (1 + apr) ** 10
