我解決一類項目,我遇到這個問題 這裏(當我追加新對象好像所有元素的數組是在同一個對象指向)是我的代碼數組元素都指向同一個對象無故
import os
from Process import Process
processes = []
# Read the file
file = open("file.txt","r")
# Read the lines
for line in file.readlines() :
# split the line components
process = line.split(";")
global processes
# append a new element to the array
pr = Process(process[0], process[1], "Ready")
# find how many elements in the line to loop through
process_len = len(process)
# loop through the line elements
for element in range(2,process_len) :
# if it's a CPU
if process[element].find("CPU") == 0:
s = process[element].split(":")
pr.add_cpu(s[1])
# if it's an IO
elif process[element].find("IO") == 0:
s = process[element].split(":")
pr.add_io(s[1])
# End of elif
processes.append(pr)
file.close()
print "-------------------------- \n";
for p in processes :
print p.getcpu()
這裏,我從讀文件:

我認爲這個問題是我要創建同一個對象的新引用和我一直把它們添加到數組作爲新的對象,但我不知道如何確保,如果是這樣的話還是我錯了如果是這種情況,我該如何解決這個問題?

@凱丹格我得到相同的輸出 – keloa
我保證它不是沒有原因的。但是你需要顯示Process類的代碼。 –
BTW,做'在全球範圍內的全球processes'是毫無意義的。請參閱[文檔](https://docs.python.org/3/reference/simple_stmts.html#grammar-token-global_stmt) –
