A method chain is also known as a train wreck due to the increase in the number of methods that come one after another in the same line that occurs as more methods are chained together even though line breaks ar
brackets and braces, or using ahanging indent[7]. When using a hanging indent the following should be considered; there should be no arguments on the first line and further indentation should be used to clearly distinguish itself as a continuation line. ...

Notice how you get the individual lines separately in stages because you defined a multiline string literal using the triple-quote ("""). The result depicted in the video above is the following: Python query_users_by_first_or_last_name = """ SELECT * FROM users WHERE first_name LIKE ...
In the highlighted line, you use the augmented addition operator (+=). With this operator, you create an assignment that’s fully equivalent to total = total + 5.Python supports many augmented assignment operators. In general, the syntax for this type of assignment looks something like this:...
multi_line_output=3 include_trailing_comma=True force_grid_wrap=0 use_parentheses=True line_length=88 The equivalent command line is: $ isort --multi-line=3 --trailing-comma --force-grid-wrap=0 --use-parentheses --line-width=88 [ file.py ] ...
Multiline strings are treated as verbose regular expressions by Black. Use [ ] to denote a significant space character. Example `pyproject.toml` [tool.black] line-length = 88 target_version = ['cpy37'] include = '\.pyi?$' exclude = ''' ( /( \.eggs # exclude a few common ...
(i.e. if ), plus a single space, plus an opening parenthesis creates a natural 4-space indent for the subsequent lines of the multiline conditional. This can produce a visual conflict with the indented suite of code nested inside the if -statement, which would also naturally be indented ...
