Python重写，而不是将数据追加到.csv文件中

我处理了50个文件，然后将每个文件的输出写入.csv文件，但它只将最后一个文件输出到.csv文件

with open('output.csv','a+') as out:
    out.write(filename)
    out.write('\n')
    out.write('\n') 
    out.write(';''Golden readback from vivado before fault-injection')
    out.write(';''Readback from vivado after the injection')
    out.write(';''Real-Delta')
    out.write('\n')
# original is my data.
    for row in original:
     for col in row:      
      out.write('{0};'.format(col))
     out.write('\n')
    out.write('\n')
out.close()  

---

知道如何将所有文件输出到同一个.csv文件中吗。

如果使用“a+”模式将结果添加到代码中，请尝试使用“w+”，它应该可以工作

with open('output.csv','w+') as out:
    out.write(filename)
    out.write('\n')
    out.write('\n') 
    out.write(';''Golden readback from vivado before fault-injection')
    out.write(';''Readback from vivado after the injection')
    out.write(';''Real-Delta')
    out.write('\n')
# original is my data.
    for row in original:
     for col in row:      
      out.write('{0};'.format(col))
     out.write('\n')
    out.write('\n')
out.close()

导入全局
从itertools导入islice
导入行缓存
路径='*.rbd'
#path='original-adder.rbd'
文件=已排序（glob.glob（路径））
对于文件中的文件名：
德鲁线=101
将open（filename，'r'）作为f：
i=1
而我只尝试使用“a”而不是a+，并且不输出。close（）使用
csv
模块创建
csv
文件。另外，
out.close（）
也不是必需的；
with
语句将隐式调用它。我已经尝试过了，但没有成功。创建.csv文件的csv模块是什么，请解释一下@chepnerIt的a。@hassan original是否拥有所有数据，或者这是您在处理完每个文件后为其运行的代码？original具有为每次运行计算的数据。它使用
file=open（'output.csv'，a+'）为原始行中的行运行@Arnab Sharmatry的每个文件：为行中的列运行：file.write（str（col））
我已经尝试过了。不知道是什么问题。可能每次输入文件都会更改吗？
