I have a python method that calculates value and returns it. The value is
我有一个python方法，计算值并返回它。价值是
CalcData = 3941269503L.
It is only 32 bit. Yet this is typecasted to long implicitly (suffixed by L) and when I access this method in COM in other application , I get the Python int too large to convert to C long error. I even tried typecasting it into int,but no luck
它只有32位。然而，这是长期隐式（后缀为L）的类型，当我在其他应用程序中的COM中访问此方法时，我得到的Python int太大而无法转换为C long错误。我甚至尝试将其转换为int，但没有运气

The "long" C type is signed so the largest positive value it can store is 2,147,483,647. The error is indeed correct, it doesn't fit.
“long”C类型已签名，因此它可以存储的最大正值为2,147,483,647。错误确实是正确的，它不适合。
Try "unsigned long" and "UL" postfix on the constant.
在常量上尝试“unsigned long”和“UL”后缀。
