導入時是否會執行.py [python3]

Question

我需要執行一個文件，所以我想知道它是否可以像這樣工作？需要執行的文件將創建一個數據庫。

Answer 1

好吧，我在這裏勾畫了答案。如果代碼沒有封裝在類或函數中，代碼將會運行。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.')
