缩进问题:Python对缩进非常敏感,确保if __name__ == "__main__":下的代码块正确缩进。 示例代码 代码语言:txt 复制 # 文件名: example.py class MyClass: def main(self): print("Running main logic in MyClass") def main(): print("Running main function") my_instance = MyClass() my_instance...
一个Python源码文件(.py)除了可以被直接运行外,还可以作为模块(也就是库),被其他.py文件导入。不管是直接运行还是被导入,.py文件的最顶层代码都会被运行(Python用缩进来区分代码层次),而当一个.py文件作为模块被导入时,我们可能不希望一部分代码被运行。 ⭐⭐ 一个.py文件被其他.py文件引用 假设我们有一个c...
