python报argumentEror:argument 1:OverflowError int too long to convert

这个错误通常出现在 Python 版本较低的时候,因为 Python 2.x 中的整型是有范围限制的,而在处理大数时会出现这个问题。解决办法是将整型转换为长整型。
在 Python 2.x 中,可以使用 long() 函数将整型转换为长整型。例如:
```
x = 1000000000000000000000000000000000000000000000000000000000000000000
y = long(x)
```
在 Python 3.x 中,整型已经没有范围限制了,因此不会出现这个错误。
如果你使用的是 Python 2.x,但不想使用 long() 函数,可以考虑使用 Python 的 decimal 模块或第三方库 gmpy2 来处理大数。

Argument 1: cannot convert from 'string' to 'int'
This error message usually occurs when you try to assign a string value to an integer variable or pass a string argument to a method that expects an integer argument. To resolve this issue, you need to convert the string value to an integer using the appropriate method.
For example, if you have a string variable named "myString" that contains an integer value, you can convert it to an integer using the Convert.ToInt32() method:
```
string myString = "123";
int myInt = Convert.ToInt32(myString);
```
Alternatively, you can use the int.TryParse() method to convert the string value to an integer safely:
```
string myString = "123";
int myInt;
if (int.TryParse(myString, out myInt))
{
// Conversion successful
}
else
{
// Conversion failed
}
```
In both cases, you will end up with an integer variable that you can use in your code without getting the "cannot convert from 'string' to 'int'" error message.
convert std::chrobo::duration to int
To convert std::chrono::duration to int, you can use the std::chrono::duration_cast function. Here's an example:
```cpp
#include <chrono>
#include <iostream>
int main() {
std::chrono::milliseconds ms{500};
int n = std::chrono::duration_cast<std::chrono::milliseconds>(ms).count();
std::cout << n << '\n'; // Output: 500
return 0;
}
```
In this example, we first create a std::chrono::milliseconds duration of 500 milliseconds. We then use duration_cast to convert it to an integer type (in this case, int) by specifying the desired duration type as the template argument. Finally, we call the count() function to retrieve the underlying integer value.
