[issue46992] If use textwrap.dedent with string formatting, may get unintended sentences.
김준환 added the comment:
x does not change.
sorry. I also haven't figured out the implementation in my head yet.
I want to provide some functionality to provide consistent indentation while
using formatting .
For example
"""
test
{multi_line_text}
""".format(multi_line_text, consistent_indent=True)
It's just a suggestion.

Sorry, Can't edit comments
Please see the code example below
```
Class A:
def get_something_string():
return textwrap.dedent("""\
test text2
test text3
test text4""")
textwrap.dedent(f"""\
test text1
{A.get_something_string()}
test text5
test text6""")
```

김준환 added the comment:
No, I know `textwrap.dedent` as a convenience function used for code
readability. But to have the result I want, I currently need to do something
like this:
If it's a method inside a class, it's even more ugly.
Class A:
def get_something_string():
return textwrap.dedent("""\
test text2
test text3
test text4""")
x = f"""\
test text1
{A.get_something_string()}
test text5
test text6"""
The duplicate use of dedent is to show an example.
Thought I needed a consistent dedent for every line while using the string
formatting feature.

[issue46992] If use textwrap.dedent with string formatting, may get unintended sentences.
김준환 added the comment:
If it's only for version 3.11, what do you think of the default behavior of the
dedent method being changed?
The method description says:
> Remove any common leading whitespace from every line in `text`.
```
def get_something_string():
return textwrap.dedent("""\
test text2
test text3
test text4""")
textwrap.dedent(f"""\
test text1
{get_something_string()} <<
test text5
test text6""")
```
I think it should work assuming that the indentation of
{get_something_string()} and the indentation of test text2 are on the same line.

[issue46992] If use textwrap.dedent with string formatting, may get unintended sentences.
New submission from 김준환 :
If use textwrap.dedent with string formatting, may get unintended sentences.
For example, a sentence like this:
```
import textwrap
def get_something_string():
return textwrap.dedent("""\
test text2
test text3
test text4""")
textwrap.dedent(f"""\
test text1
{get_something_string()}
test text5
test text6""")
```
I look forward to the following results.
```
test text1
test text2
test text3
test text4
test text5
test text6
```
But the actual result is:
```
test text1
test text2
test text3
test text4
test text5
test text6
```
I understand that this code works in this way because the intent of the string
defined inside the method is different from the intent of the string outside
the method.
However, regular users, like me, will think of having a consistent intent
result value. (because they believe dedent will clear a consistent intent)
If you are concerned that the existing code will be broken, I can implement
the function using the flag parameter.
If you agree with my opinion, I will submit a PR.
