每行缩进打印

Question

Is there a way in python to print something, say foo = "The Title of The Message\n\tThe first paragraph of the message" with a tab appended to each line, without modifiying my variable, ( foo in this example).

The result I want would be: The Title of The Message The first paragraph of the message"

I'm looking for something similar to when you do a git log , the message of the commit is always indented

Answer 1

I'm not quite sure what you expect here. No, there isn't an automatic formatting tool to do this. However, you can certainly copy the value and modify that , or print an in-line alteration. For instance:

print foo.replace("\n", "\n\t")

string.replace returns an altered copy of the string.

Answer 2

Don't know of any builtins / standard ways of doing it, but you could do a single tab with Prune's simple solution ( print foo.replace('\\n', '\\n\\t') ), or if you want it more general for any number of leading tabs:

>>> def print_indented(n, s):
...     """Print a string `s` indented with `n` tabs at each newline"""
...     for x in s.split('\n'):
...         print '\t'*n + x
...
>>> foo = "The Title of The Message\n\tThe first paragraph of the message"
>>> print_indented(1, foo)
        The Title of The Message
                The first paragraph of the message
>>> print_indented(2, foo)
                The Title of The Message
                        The first paragraph of the message

The '\\t'*n bit repeats the tab character n times.

This can now be done with the textwrap module, specifically itsindent function.

Example:

import textwrap


foo = "The Title of The Message\n\tThe first paragraph of the message"
print(textwrap.indent(foo, '\t'))

Output:

        The Title of The Message
                The first paragraph of the message

There is an optional predicate argument which can be used to control which lines are indented, eg you might want to ignore empty lines and whitespace-only lines to not add unnecessary extra spaces.
