Backslashes may still be appropriate at times. For example, long, multiplewith-statements cannot use implicit continuation, so backslashes are acceptable: with open('/path/to/some/file/you/want/to/read') as file_1, \ open('/path/to/some/file/being/written', 'w') as file_2: file_2.w...
First, you add .interest as a new attribute and .add_interest() as a new method for adding interest to the savings account. Next, you update .from_balance() to support specifying the interest. Since this constructor overrides the corresponding method in BankAccount, you mark it with @...
Python accepts the control-L (i.e. ^L) form feed character as whitespace; Many tools treat these characters as page separators, so you may use them to separate pages of related sections of your file. Note, some editors and web-based code viewers may not recognize control-L as a form f...

We can use backslashes to escape special characters within custom character sets. For example, ‘[]’ matches a left or right square bracket. Negation can be combined with character escapes. ‘[^]’ matches any character, not a square bracket. ...

If a user needs to define the path or route of a particular file, note that the path itself includes backslashes. To include a backslash in the string, precede it with another backslash. Example: F:\\Admin\\Host\\Files Raw strings can be used to avoid unnecessary backslashes in paths. ...
# Add some extra indentation on the conditional continuation line. # 在条件判断语句所在行添加一些额外的缩进 if (this_is_one_thing and that_is_another_thing): do_something() The closing brace/bracket/parenthesis on multi-line constructs may either line up under the first non-whitespace character...
One exception to adding trailing commas is function signatures containing*,*args, or**kwargs. In this case a trailing comma is only safe to use on Python 3.6.Blackwill detect if your file is already 3.6+ only and use trailing commas in this situation. If you wonder how it knows, it lo...
