在python中，如何读取json文件作为输入，获取txt文件作为输出#jupyter笔记本

Question

我正在编写一个代码来分析JSON文件。我希望我的输出是一个txt文件。代码如下

inputFile = "C:\Users\nk\Documents\survey\data.json"
outfile= "C:\Users\nk\Documents\survey\data_summary.txt"
json_file = open(inputFile, 'r', encoding="utf8")
jsondb = json.load(json_file)

fs = open(outFile, 'w')

#some loops in between

fs.flush()
fs.close()

在jupyter笔记本中运行此代码后，它会显示如下错误

inputFile = "C:\Users\nk\Documents\survey\data.json"              ^
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escap

怎么办？怎么写？？？我是编程新手

您可以使用以下三种方式之一正确表示文件路径：

1) inputFile = "C:/Users/nk/Documents/survey/data.json"
   outfile= "C:/Users/nk/Documents/survey/data_summary.txt"

2) inputFile = "C:\\Users\\nk\\Documents\\survey\\data.json"
   outfile= "C:\\Users\\nk\\Documents\\survey\\data_summary.txt"

or as Charnel pointed out:

3) inputFile = r"C:\Users\nk\Documents\survey\data.json"
   outfile= r"C:\Users\nk\Documents\survey\data_summary.txt"
