Python將多個數組寫入爲csv

我有一個正確運行並打印值的opencv python程序。但是，當我嘗試將打印的值寫入csv文件時，出現錯誤。以下是代碼：Python將多個數組寫入爲csv

for testingPath in paths.list_images(args["testing"]): 
    # load the image and make predictions 
    image = cv2.imread(testingPath) 
    boxes = detector(cv2.cvtColor(image, cv2.COLOR_BGR2RGB)) 
    # loop over the bounding boxes and draw them 
    for b in boxes: 
     (x, y, w, h) = (b.left(), b.top(), b.right(), b.bottom()) 
     cv2.rectangle(image, (x, y), (w, h), (0, 255, 0), 2) 
     #print(basename(testingPath),"CX:"+str(x),"CY:"+str(y),"Width:"+str(w),"Height:"+str(h),brandname,"Number of brands detected: {}".format(len(boxes))) -----this prints all the required values without problem on the console

我試圖這樣做：

我添加的參數之前，對循環開始：

ap.add_argument("-i", "--index", required=True, help="Path to directory of output") 
output = open(args["index"], "w")

和所用的環如下：

for testingPath in paths.list_images(args["testing"]): 
    # load the image and make predictions 
    image = cv2.imread(testingPath) 
    #filename = testingPath[testingPath.rfind("/") + 1:] 
    boxes = detector(cv2.cvtColor(image, cv2.COLOR_BGR2RGB)) 
    #print(basename(testingPath), brandname,"Number of brands detected: {}".format(len(boxes))) 
    # loop over the bounding boxes and draw them 
    for b in boxes: 
     (x, y, w, h) = (b.left(), b.top(), b.right(), b.bottom()) 
     cv2.rectangle(image, (x, y), (w, h), (0, 255, 0), 2) 
     #print(basename(testingPath),"CX:"+str(x),"CY:"+str(y),"Width:"+str(w),"Height:"+str(h),brandname,"Number of brands detected: {}".format(len(boxes))) 
     dat = str([x, y, w, h, brandname, len(boxes)]) 
     output.write("{},{}\n".format(testingPath, "".join(dat)))

上面的代碼打印值如下：

/home/mycomp/VideoExtract/28157.jpg,[83, 349, 164, 383, 'Pirelli', 1]

我想擺脫[]括號。所需的操作是將打印的值寫入csv /文本文件。

以CSV格式寫入數據是一項非常普遍的任務 - 您可以使用library called csv。

讓你的輸出變量中的CSV作家

output = csv.writer(open(args["index"], "w"))

這一行

output.writerow((testingPath, x, y, w, h, brandname, len(boxes)))

此示例代碼不打算提出建議，以改善更換您的最後兩行

dat = str([x, y, w, h, brandname, len(boxes)]) output.write("{},{}\n".format(testingPath, "".join(dat)))

代碼質量和/或可讀性。 –

謝謝....這個改變奏效了。 – Apricot
