仅在确定循环中打印最后一个值

Question

如何打印确定范围内的最后一个值？def main(): print "This program calculates the future value of a 10-year investment." principal = input("Enter the initial principle: ") apr = input("Enter the annual interest rate: ") for i in range(10):  principal = principal * (1 + apr)  print "The value in 10 years is:", principal 输出：The value in 10 years is XXXXXXXThe value in 10 years is XXXXXXXThe value in 10 years is XXXXXXXThe value in 10 years is XXXXXXXThe value in 10 years is XXXXXXXThe value in 10 years is XXXXXXXThe value in 10 years is XXXXXXXThe value in 10 years is XXXXXXXThe value in 10 years is XXXXXXXThe value in 10 years is XXXXXXX如何仅打印循环的最后一次迭代？

Answer 1

取消最后一行的缩进（请不要再使用1个空格缩进，PEP-8建议使用4个空格）

def main():

    print "This program calculates the future value of a 10-year investment."

    principal = input("Enter the initial principle: ")

    apr = input("Enter the annual interest rate: ")

    for i in range(10):

        principal = principal * (1 + apr)

    print "The value in 10 years is:", principal 

Answer 2

只需将print行移出for-loop即可：

for i in range(10):

    principal = principal * (1 + apr)

print "The value in 10 years is:", principal 

Answer 3

  with open("story.txt",encoding="utf-8") as f:

        for line in f:

            for word in line.split()

                aList.append( word )

        print(aList)
