我是一名新的Python学习者。这是我在名为test2.py的Python文件中编写的函数，该函数在名为app02.py的Python文件中的基于web.py的应用程序中调用。

def myfunc(a,b,c):
d = {1:"US", 2:"CN", 3:"UK", 4:"Di", 5:"Wu", 6:"Ji", 7:"Ge", 8:"Xi", 9:"Re", 10:"Ku"}

f = int(a) - 3
g = (f)%10
h = (f)%12
a_num = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
b_num = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
if g in a_num:
i = d[g]
elif g == 0:
i = d[10]
if h in b_num:
j = e[h]
elif h == 0:
j = e[12]
a_text = "%s is %s %s" % (str(a), i, j,)
k = {1:"Good", 2:"Bad", 3:"Very Good", 4:"Very bad", 5:"Not sure", 6:"sure", 7:"somehow", 8:"what", 9:"You", 10:"Nothing"}

if i == d[1]:
l = k[5]

b_text = "and its l is %s" % (l)
m = ("CHN", "GBP", "USD", "CND", "MSN", "WED")
if j == e[1] or j == e[7]:
n = m[1]
o = m[4]
elif j == e[2] or j == e[8]:
n = m[2]
o = m[5]
elif j == e[3] or j == e[9]:

elif j == e[4] or j == e[10]:
n = m[4]
o = m[1]
elif j == e[5] or j == e[11]:
n = m[5]
o = m[2]
elif j == e[6] or j == e[12]:
n = m[0]
o = m[3]
c_text = "the n is %s, the o is %s" % (n, o)
c_num = m.index(n)
if (b == 1 and (c >= 21 and c <= 31)) or (b == 2) or (b == 3 and c <= 21):
p = m[0]
q = m[c_num - 2]
elif (b == 3 and (c >= 21 and c <= 31)) or (b == 4) or (b == 5 and c <= 21):
p = m[1]
q = m[c_num - 1]
elif (b == 5 and (c >= 21 and c <= 31)) or (b == 6) or (b == 7 and c <= 21):
p = m[3]
q = n
elif (b == 7 and (c >= 21 and c <= 31)) or (b == 8) or (b == 9 and c <= 21):
p = m[2]
q = m[c_num + 1]
elif (b == 9 and (c >= 21 and c <= 31)) or (b == 10) or (b == 11 and c <= 21):
p = m[4]
q = m[c_num + 2]
elif (b == 11 and (c >= 21 and c <= 31)) or (b == 12) or (b == 1 and c <= 21):
p = m[5]
q = o
else:
p = "Wrong input!"
q = "Wrong input!"
d_text = "The p is %s and the q is %s." % (p, q)
return a_text, b_text, c_text, d_text
当我在Python编译器中运行该函数时，它运行良好，因为它可以很好地返回d_text。例如：
>>> import test2
>>> test2.myfunc(1980,3,4)
('1980 is Ge Sh', 'and its l is somehow', 'the n is CND, the o is CHN', 'The p is CHN and the q is GBP.')
以下是基于web.py的app02.py，它将调用上面的函数。然后问题来了，因为它无法很好地返回d_text，这会导致“else”结果。但是我希望它能像上面的Python编译器那样做，它会转到“if / elif”结果。
# -*- coding: utf-8 -*-
import web
import test2
urls = (
'/dyear', 'Index'
)
app = web.application(urls, globals())
render = web.template.render('/Users/Administrator/projects/gothonweb/templates/', base="layout01")
class Index(object):
def GET(self):
return render.hello_form01()
def POST(self):
form01 = web.input(a_year=1980)
form02 = web.input(a_month=01)
form03 = web.input(a_day=01)
greeting = "Your result from app02 is %s." % ((str(test2.myfunc(form01.a_year, form02.a_month, form03.a_month))))
return render.index(greeting = greeting)
if __name__ == "__main__":
app.run()
当我尝试在web.py上运行app02.py时输入（1980,3,4）这样：
然后我得到了web_py返回错误的d_text响应，如下所示：
那么为什么同样的函数在Python编译器和web.py应用程序中有不同的结果？谢谢。
答案 0 :(得分：0)
web.py将值作为字符串传递，而不是整数。
您可以通过在解释器中使用字符串vs int运行脚本来查看此内容。
datetime作为旁注，您的代码可以通过使用更多描述性变量名来改进，使用{{1}}来解析输入并重构以删除if语句（可能使用字典来映射输入 - 而不是输出）

web.input()返回类似dict的结构。您想要一个特定的值：
form01 = web.input(a_day=1).a_day
将获得整数值。关于web.py传递字符串的其他注释并不完全正确。 HTTP（通常）传递字符串值，但`web.input（）将根据您初始化的方式转换它们：
a_str = web.input(a_day='1').a_day
a_int = web.input(a_day=1).a_day
a_float = web.input(a_day=1.0).a_day
正如其他人所建议的那样，将来你应该打印出你的返回值，以便真正看到你得到的东西！
