在VSCode中運行時的Python跳過函式

我撰寫了以下 python 代碼以將 XYZ 資料讀取為 CSV，然后將網格轉換為 GTiff 格式。

當我運行代碼時，我沒有收到任何錯誤。

但是，在嘗試除錯之后，我添加了一些列印陳述句并注意到實際上并沒有呼叫這些函式。

如何運行此腳本以使其全部完成？

用

if __name__ == "__main__":
    app = gdal_toolbox(kwargs)
    app.run()

或者

 if __name__ == "__main__":
    gdal_toolbox(kwargs).run()

在腳本末尾使用這些代碼。

解決方案是：

class gdal_toolbox:

    ## CONSTANTS ##

    def __init__( self, kwargs ):
        print(kwargs)



    def normalizeToCsv( self ):
            MAX_POINTS = 64000000
            print(MAX_POINTS)

        

    def csvToTiff(self):

          print("Its the secoend function")
      
      
if __name__ == "__main__":
 
    kwargs="Its the keyword arguments"
    gdal_toolbox(kwargs)

在這段代碼中，您似乎沒有執行任何操作，只是在其中定義了類和函式，對嗎？
