Go 语言没有 while 和 do...while 语法,这一点需要同学们注意一下,如果我们需要使用类似其它语 言(比如 java / c 的 while 和 do...while ),可以通过 for 循环来实现其使用效果。 while 循环的实现 Ø 说明上图 1) for 循环是一个无限循环 2) break 语句就是跳出 for 循环 Ø 使用上面的 while ...

i 在for循环外被初始化成了 0。只要i<=10循环就会被执行。在循环中,i 以 2 的增量自增。上面的程序会输出0 2 4 6 8 10。 上面程序中for循环中的分号也可以省略。这个格式的for循环可以看作是二选一的for while循环。上面的程序可以被重写成: package mainimport("fmt") func main() { i :=0fori ...

What did you do? I encountered this issue on macOS while importing two Python extensions written in Go usingPygolo. I could reduce the problem to the following repro, completely removing Python from the picture. This is a minimal shared library exporting a dummy function: ...
