python - 如何在python的嵌套循环中运行字符串数组

Question

我尝试运行这段代码（我的程序的一小部分）我修复并添加了空格，现在我得到了新的错误，也许这个数组不适合字符串？

arrayOfPhotos = ["1.jpg", "2.jpg", "3.jpg", "4.jpg"]

for name in arrayOfPhotos:
  detections = detector.detectObjectsFromImage(input_image=arrayOfPhotos[name], output_image_path="holo3-detected.jpg")

  for detection in detections: 
    print(arrayOfPhotos[name], " : ", detection["percentage_probability"])

我得到错误：

Traceback (most recent call last):
  File "dTEST.py", line 13, in <module>
    detections = detector.detectObjectsFromImage(input_image=arrayOfPhotos[name], output_image_path="holo3-detected.jpg")
TypeError: list indices must be integers or slices, not str

你能帮助我吗？

Answer 1

你可能想要的是这个：

arrayOfPhotos = ["1.jpg", "2.jpg", "3.jpg", "4.jpg"]

for name in arrayOfPhotos:
  detections = detector.detectObjectsFromImage(input_image=arrayOfPhotos[name], output_image_path="holo3-detected.jpg")

  for detection in detections: 
    print(arrayOfPhotos[name], " : ", detection["percentage_probability"])

空格在 python 中很重要，对于要成为循环的一部分的语句，它需要与循环缩进（我在行前添加了 2 个空格）

编辑：OP编辑了问题。

将 input_image=arrayOfPhotos[name] 替换为 input_image=name

Answer 2

arrayOfPhotos = ["1.jpg", "2.jpg", "3.jpg", "4.jpg"]

for name in arrayOfPhotos:
    detections = detector.detectObjectsFromImage(input_image=name, output_image_path="holo3-detected.jpg")

    for detection in detections: 
        print(name, " : ", detection["percentage_probability"])

照片数组是一个列表而不是字典......
