我正在使用共享數組在 Python 中運行多進程代碼。問題是我無法初始化那個數組...要在我讀過的多進程程序中共享一個數組我需要使用 multiprocessing.Array，但是當我在下面的代碼中嘗試它時它沒有打印任何東西+ 我沒有錯誤信息。import multiprocessing......if __name__ == "__main__": an_array= multiprocessing.Array("i", [1,2]) print(an_array) # why does it not print anything? I was expecting to print [1,2] p1 = multiprocessing.Process(target=function1, args = [an_array, 3]

要在 中打印元素，Array請執行以下操作：
import multiprocessing
if __name__ == '__main__':
an_array = multiprocessing.Array("i", [1, 2])
# first choice to print element in Array:
for element in an_array:
print(element)
# second choice to print elements in Array:
print(an_array[:])
# third choice to print elements in Array:
print(list(an_array[:]))
