Question

我尝试按分隔符"}.分割文件，但是找不到分隔符，结果我只得到一个新文件，其内容与原始文件相同。代码是：

with  open('okladki_200_01') as fp:
    contents = fp.read()

    i = 1
    for entry in contents.split('"}.'):

        f= open("okladka_%s" % i,"w+")
        f.write(entry)
        f.close()
        i += 1

可以帮忙吗？

编辑：该文件的内容如下：

{"base64Image":"/9j/4AAQSkZJRgABAQAAAQABAAD/2wBDAAEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEB\nAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQH/2wBDAQEBAQEBAQEBAQEBAQEBAQEBAQEB\nAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQH/wAARCAusFMADASIA\nAhEBAxEB/8QAHwAAAgIBBQEBAAAAAAAAAAAAAgQAAwUBBgcICQoL/8QAaRAAAQEFBAcDBwgHBQYD\nAwEZAwIBBBESEwAhIiMFFDEyM0FDUVNhBiRCY3GBkQcIFTRSc6GxRGKDk8HR8FRyo+HxCRYlZLPD\ndILTFzWEkp [...] 3aIiVoL1pmNQxjWr27\nPBnhatT94NfdwDzDBz9aSP/Z\n","elementHashcode":-1794239528,"imageOrientation":6,"type":"BOOK"}

我想我刚刚发现了问题... HxD查看器将0x0A ASCII字符显示为点，但这是换行符。所以我应该寻找'"}\n'

Answer 1

将contents.split（'“}。'）移至其自己的变量中。

lines = contents.split('.}"')

for entry in lines: 
    ...

代码：

with  open('textfile') as fp:
    contents = fp.read()

i = 1

lines = contents.split('.}"')

for entry in lines: 
    f= open("textfile_%s" % i,"w+")
    f.write(entry)
    f.close()
    i += 1

fp.close()

您是否真的需要检查方括号？在您的情况下，您的输入文件似乎已经被格式化为1个内容= 1行，因此我们的分隔符可以改为\n，而我们可以使用readlines()。

这是一个可能的解决方案：

with  open('okladki_200_01') as fp:
    lines = fp.readlines() # this is a list of strings.

    i = 1
    for line in lines:
        entry = line.lstrip("{").rstrip("}\n") # some clean-up.
        f = open("okladka_%s" %i ,"w+")
        f.write(entry)
        f.close()
        i += 1
