In this example, you use a tuple of values as the right-hand operand to %. Note that you’ve used a string and an integer. Because you use the %s specifier, Python converts both objects to strings.You can also use dictionaries as the right-hand operand in your interpolation expressions...
OverflowError: Python int too large to convert to C long是一个常见但容易规避的错误。通过理解Python和C语言的整数表示差异,合理使用Python的原生类型,并在必要时进行适当的数据检查,我们可以有效避免这一错误的发生。希望通过本文的讲解,大家能更加从容地应对这类问题,提升代码的健壮性。 希望本文对你有所帮助。...
