Split text file into smaller ones by bytes in python
I have a problem with splitting a large text file into smaller files by the size (in bytes)
e.g. text file has 30kB, I want to split it into multiple files with 5kB each.
I search a lot but I found almost ways split the file by lines.
any suggestions?

If you are looking into splitting it into files of uniform size (e.g. 5KB each), then one solution would be:
- Read the large file as binary
- For every 5000 bytes (5KB), create a new file
- Write those 5000 bytes into the new file
Sample code:
i = 0
with open("large-file", "r", encoding="utf8") as in_file:
bytes = in_file.read(5000) # read 5000 bytes
while bytes:
with open("out-file-" + str(i), 'w', encoding="utf8") as output:
output.write(bytes)
bytes = in_file.read(5000) # read another 5000 bytes
i += 1
thanks for your answer, but it doesn't work fine with Unicode texts.

in writing part, when I read segmented files, it views unreadable characters.

can you paste some of the characters here? it might be an issue with the encoding
