Question

我想使用下面显示的代码来计算该期间的年度总租金。

非常感谢任何帮助。

rent_rate = input('please enter the price per square foot:')   # price sq/ft
lease_rate = input('please enter the rate of the lease:')           # interest rate
lease_term = input('please enter the tenor (in years) of the lease:')  
size_of_space = input('please enter the size(in square feet) of the space:')  

print "Year %25s" % "Rent Rate%25s"  % "Rate%25s" % "Square Feet%25s" % "Yearly Rent%25s" % "Monthly Rent"


for year in range( 0, lease_term ):
   rent_rate = principal * ( 1.0 + rate ) ** year
   yearly_rent = rent_rate * size_of_space
   monthly_rent = yearly_rent/12
   print "%4d%21.2f%21.2f%21.2f%21.2f%21.2f" % ( year + 1, rent_rate, rate, size_of_space, yearly_rent, monthly_rent)

我认为你需要做一些事情！您应该指定＆＃39; principal＆＃39;以及＆＃39; rent_rate＆＃39;因为它们是凭空而来的！

另外，如果用户输入的是数字，你应该做＆＃39; int＆＃39;或者＆＃39;漂浮＆＃39;那些投入！这里：

rent_rate = float(input('please enter the price per square foot:'))   
lease_rate = float(input('please enter the rate of the lease:'))       
lease_term = int(input('please enter the tenor (in years) of the lease:'))  
size_of_space = float(input('please enter the size(in square feet) of the space:'))  

print "Year %25s" % "Rent Rate%25s"  % "Rate%25s" % "Square Feet%25s" %  "Yearly Rent%25s" % "Monthly Rent"


for year in range(0, lease_term):
   rent_rate = principal * ( 1.0 + rate ) ** year
   yearly_rent = rent_rate * size_of_space
   monthly_rent = yearly_rent/12
   print "%4d%21.2f%21.2f%21.2f%21.2f%21.2f" % ( year + 1, rent_rate, rate,     size_of_space, yearly_rent, monthly_rent)

就像风格一样 - 在线评论应该谨慎进行。查看python Pep 8风格指南！
