运行模板文件中的函数 (Python/Bottle)

Question

我正在使用 bottle 创建一个简单的退休计算器，但我在处理 python 代码的模板文件时遇到了问题。例如，我有这个代码

<%
import statistics, numpy

medianStockReturn = []

def stockReturn():
    global medianStockReturn
    yearStockReturn = numpy.random.normal(11.4, 19.7, 1000)
    yearMedianStockReturn = statistics.median(yearStockReturn)
    yearMedianStockReturn = yearMedianStockReturn / 100 + 1
    medianStockReturn.append(yearMedianStockReturn)
stockReturn()
end
%>

<!DOCTYPE html>
<html lang = "en-us">
    <head>
        <title>Retirement Calculator</title>
        <meta charset = "utf-8">
        <link rel="stylesheet" type="text/css" href="../static/retirementStyle.css">
   </head>
   <body>
       <h2> this is a test; your stock return is {{medianStockReturn}}</h2>
   </body>
</html>

但是，此代码的输出结果为："this is a test; your stock return is []"

正如所写，该函数应该将生成的值附加到 medianStockReturn 上，但它没有，我也不确定为什么。

Answer 1

您需要将 end 移动到上面函数定义结束后 stockReturn()

<%
import statistics, numpy

medianStockReturn = []

def stockReturn():
    global medianStockReturn
    yearStockReturn = numpy.random.normal(11.4, 19.7, 1000)
    yearMedianStockReturn = statistics.median(yearStockReturn)
    yearMedianStockReturn = yearMedianStockReturn / 100 + 1
    medianStockReturn.append(yearMedianStockReturn)
end
stockReturn()
%>

<!DOCTYPE html>
<html lang = "en-us">
    <head>
        <title>Retirement Calculator</title>
        <meta charset = "utf-8">
        <link rel="stylesheet" type="text/css" href="../static/retirementStyle.css">
   </head>
   <body>
       <h2> this is a test; your stock return is {{medianStockReturn}}</h2>
   </body>
</html>
