在 python 中将文本数据从一个 txt 文件复制到另一个文件时出现问题

Question

I have a file text.txt that contains text data: this is a text file
then I have a test.text that is primarily empty.

from sys import argv

script, from_file, to_file = argv

out_file = open(to_file, 'w').write((open(from_file).read()))

when I run that code the test.txt file gets copied text from text.txt file and it is:

this is a text file਍ഀ
਍ഀ

why do I get those rectangular blocks?? How to fix it??

Answer 1

If you look closely at the "rectangular blocks" you can see that they contain the rows

0A

and

0D

which are the hex representations of '\n' and '\r' respectively. So the blocks are your editor's way of showing you these characters, which are used in Windows to mark the end of a line in a text file and which are usually invisible.
