导入时是否执行.py [python3]

Question

我需要执行一个文件，所以我想知道它是否像这样工作？需要执行的文件将创建一个数据库。

Answer 1

好的，我也在这里勾勒出答案。如果代码未封装在类或函数中，则代码将运行。例如：

def f():
    print ('This line will not be executed during import from another file')

print ('This line is executed!')

if __name__ == '__main__':
    print ('This line is executed only, if the program is main program, but not during import from another program.')
