Python's transfer character (study Note III)

Python's transfer character (study Note III)

Escape character \ Can escape many characters, such as \ n for newline, \ t for tab, character \ itself to escape, so \ \ means the character is \, you can print a string in Python's interactive command line to see:

Command:

>>>print ' he\ ' s a boy. '

>>>print ' I\ ' m learning\nlinux. '

>>>print ' \\\n\\ '

If there are many characters in the string that need to be escaped, you need to add a lot of \, in order to simplify, Python also allows to use R ' ' to indicate that the string inside of ' is not escaped by default, for example:

Command:

print ' \\\ ' n\\

Print R ' \\\ ' n\\ #r与引号之间是没有空格的!

• Extended

If there is a lot of line wrapping inside the string, it is not good to read it in a line, in order to simplify, Python allows "..." format to represent multiple lines of content, for example:

Note:

Multi-line string ' ... ' You can also add R to the front, so the example above can be written as well.
