Follow the line length guidelines with long strings without including any extra blanks or newlines?-CodePudding

I am trying to write a one-line long string in Python but I would like to follow the line length guidelines by showing it in multiple lines in the editor.

Problem Example:

long_string = "This is a very long string. Since it is a one-line string, I really want to keep it without any new line. However, I don't like how it looks in my code and it is annoying me"

I would like to achieve something similar to this (more readable and tidy):

long_string = "This is a very long string. Since it is a one-line string, I really want \
               to keep it without any new line. However, I don't like how it looks in my \
               code and it is annoying me"

However, the output adds spaces and/or newlines:

This is a very long string. Since it is a one-line string, I really want                to keep it without any new line. However, I don't like how it looks in my                code and it is annoying me

Although I know that there are ways to achieve it (as the following examples), in my opinion, these ways are not so easy to maintain:

long_string = "".join(["This is a very long string."],
                      ["Since it is a one-line string, I really want"],
                      ["to keep it without any new line. However, I don't like how"],
                      ["it looks in my code and it is annoying me"])

long_string = ("This is a very long string."
               "Since it is a one-line string, I really want"
               "to keep it without any new line. However, I don't like how"
               " ...")

Does anyone know an easier way to tackle this problem? Thanks.

CodePudding user response：

The way that requires neither repeated quotes, nor backslash line terminators (both of which impede editing the text because those characters have to be moved around) is to use a triple-quoted string and then strip newlines.

long_string = """
This is a very long string. Since it is a one-line string, I really want to
 keep it without any new line. However, I don't like how it looks in my code
 and it is annoying me
""".replace('\n', '')

This works as-is when in module scope and flush left. In an indented block it's also possible within stdlib:

from textwrap import dedent


def foo():
    long_string = dedent("""
    This is a very long string. Since it is a one-line string, I really want
     to keep it without any new line. However, I don't like how it looks in
     my code and it is annoying me
    """).replace('\n', '')
    print(long_string)


foo()
