Moves the cursor left (but may "backwards wrap" if cursor is at start of line). ^I: 0x09: HT: Tab: Moves the cursor right to next tab stop. ^J: 0x0A: LF: Line Feed: Moves to next line, scrolls the display up if at bottom of the screen. Usually does not move horizontally, though programs should not rely on this. ^L: 0x0C: FF: Form Feed: Move a ...
Ctrl+s : Go back to the next more recent command of the reverse search (beware to not execute it from a terminal because this command also launches its XOFF). If you changed that XOFF setting, use Ctrl+q to return. Ctrl+t : Transpose the previous two characters. Ctrl+u : Clears the line content before the cursor and copies it into the clipboard.
The if clause body starts on line 3 since it is indented an additional level, and ends on line 4 since line 5 is indented a level less, a.k.a. outdented. The colon (:) at the end of a control statement line is Python syntax; not an aspect of the off-side rule. The rule can be realized without such colon syntax.
Python sets are very much like mathematical sets, and support operations like set intersection and union. Python also features a frozenset class for immutable sets, see Collection types. Dictionaries (class dict) are mutable mappings tying keys and corresponding values. Python has special syntax to create dictionaries ({key: value})

For years in HTML, a table has always forced an implicit line-wrap (or line-break). So, to keep a table within a line, the workaround is to put the whole line into a table, then embed a table within a table, using the outer table to force the whole line to stay together. Consider the following examples: Wikicode (showing table forces line-break)
Bash can execute the vast majority of Bourne shell scripts without modification, with the exception of Bourne shell scripts stumbling into fringe syntax behavior interpreted differently in Bash or attempting to run a system command matching a newer Bash builtin, etc. Bash command syntax includes ideas drawn from the Korn Shell (ksh) and the C ...
When using justification, it is customary to treat the last line of a paragraph separately by simply left or right aligning it, depending on the language direction. Lines in which the spaces have been stretched beyond their normal width are called loose lines , while those whose spaces have been compressed are called tight lines .
