我是JSON的新手,我想从python脚本生成一个JSON文件
例如:
#take input from the user
num = int(input("Enter a number: "))
# prime numbers are greater than 1
if num > 1:
#check for factors
for i in range(2,num):
if (num % i) == 0:
print(num,"is not a prime number")
print(i,"times",num//i,"is",num)
break
else:
print(num,"is a prime number")
# if the input number is less than or equal to 1, it is not prime
else: print(num,"is not a prime number")
对于上面的python脚本,如何生成JSON文件?有没有工具或软件?
我不想手动创建JSON文件。上面的代码只是一个例子。
我有一个用于对象检测和多个输入图像的代码。在每个图像中,对象是相同的,但对象的位置是不同的。
inputImage:Trolley_Problem
tramTemplate:tram1
更新1:
import numpy as np
import cv2
# Read the main image
inputImage = cv2.imread("Trolley_Problem.jpg")
# Convert it to grayscale
inputImageGray = cv2.cvtColor(inputImage, cv2.COLOR_BGR2GRAY)
# Read the templates
tramTemplate = cv2.imread("tram1.jpg")
# Convert the templates to grayscale
tramTemplateGray = cv2.cvtColor(tramTemplate, cv2.COLOR_BGR2GRAY)
#Store width and height of the templates in w and h
h1,w1 = tramTemplateGray.shape
# Perform match operations.
tramResult = cv2.matchTemplate(inputImageGray,tramTemplateGray, cv2.TM_CCOEFF_NORMED)
# Specify a threshold
threshold = 0.75
# Store the coordinates of matched area in a numpy array
loc1 = np.where( tramResult >= threshold)
for pt in zip(*loc1[::-1]):
cv2.rectangle(inputImage,pt, (pt[0] + w1, pt[1] + h1), (0,255,255), 1)
cv2.putText(inputImage,"Tram Detected", (200,50), font, 0.5, 255)
# Show the final result
cv2.imwrite(r "Trolley_Problem_Result.jpg", inputImage)`
因此,我必须为此对象检测程序生成JSON文件。
谢谢

以下是将json模块与字典一起使用的示例
import json
# make sample dict with comprehension
dict1 = {k: v for (k, v) in enumerate(range(10))}
json1 = json.dumps(dict1)
具有以下值
'{"0": 0, "1": 1, "2": 2, "3": 3, "4": 4, "5": 5, "6": 6, "7": 7, "8": 8, "9": 9}'
所以,创建一个dict,使用模块。
