returnfrommain()function报错是微软系统出故障了。根据查询相关资料得知，关闭电脑后静置几分钟，再重启电脑，要是这个情况还没有恢复，就需要联系电脑的品牌售后方。
python __main__ return报错 python中return outside function 一、递归 1、定义: 在函数内部,可以调用其他函数。如果一个函数在内部调用自身本身,这个函数就是递归函数。 (1)递归就是在过程或函数里调用自身; (2)在使用递归策略时,必须有一个明确的递归结束条件,称为递归出口。 1 def age(n): 2 if n ==...
__name__ value: python_main_function Done 1. 2. 3. Notice that first two lines are getting printed frompython_main_function.pysource file. Notice the value of__name__is different and hence main method is not executed. 注意,前两行是从python_main_function.py源文件中打印出来的。 请注意,...

从报错信息来看，问题出在main函数的返回值上。仅仅写下return语句时，编译器会假设返回类型为void，而int main的定义要求返回类型是int。因此，为了符合标准，应将return语句修改为return 0；在C语言编程中，main函数的返回值具有重要的意义。它不仅表明程序是否成功执行完毕，还可能返回给操作系统一些信息。

在x == 5循环迭代中(但在 之前co_yield),我们的流程(在 CSP 意义上)应该像这样链接main - filter(3) - filter(2) - source:在调试器中重新编译和运行证实了这一点:从下往上,堆栈跟踪显示main,filter两次然后source。 Recall thatlogically(and in the source code), the filter function takes two argume...
