用Python从.json文件中删除特定行？

Question

这里的问题是，我可以删除我的文件夹行，但我不能选择他们作为他们的相似方式

例如，我有一个包含3000行的.json文件，需要删除以"navig"开头的行。我们如何修改Python代码

with open("yourfile.txt", "r") as f:
    lines = f.readlines()

with open("yourfile.txt", "w") as f:    
    for line in lines:
        if line.strip("\n") != "nickname_to_delete":
            f.write(line) 

（代码取自另一个答案。）

你可以这样做：

with open("yourfile.txt", "r") as f:
    lines = f.readlines()

with open("yourfile.txt", "w") as f:    
    for line in lines:
        if not line.startswith(YOUR_SEARCH_STRING):
            f.write(line)

或者如果只想写一次文件：

with open("yourfile.txt", "r") as f:
    lines = f.readlines()

lines_to_write = [line for line in lines if not line.startswith(YOUR_SEARCH_SRING)]

with open("yourfile.txt", "w") as f:    
    f.write(''.join(lines_to_write))
