Question

我处理了50个文件，然后将每个文件的输出写入.csv文件，但是，它只给我输出到.csv文件的最后一个文件

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。

Answer 1

您使用＆＃39; a +＆＃39;将结果附加到代码中模式，尝试＆＃39; w +＆＃39;相反，它应该工作。

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()

Python重写而不是将数据附加到.csv文件中
