导入时是否会执行.py [python3]

Question

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

Answer 1

好吧，我在这里勾画了答案。如果代码没有封装在类或函数中，代码将会运行。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.')
