Indentation and Wrapping¶
Indentation is a common way to display data hierarchically.
help you manage it. For example:
say('ITEMS') for item in items: say(item, indent=1)
will indent the items by one indentation level (by default, each indent
level is four spaces, but
you can change that with the
If you want to change the default indentation level:
say.set(indent=1) # to an absolute level say.set(indent='+1') # strings => set relative to current level ... say.set(indent=0) # to get back to the default, no indent
Or you can use a
with say.settings(indent='+1'): say(...) # anything say() emits here will be auto-indented +1 levels # anything say() emits here, after the with, will not be indented +1
If using a string to indicate relative indent levels offends your sense of
dimensionality or strict typing, there is a class
Relative that does the same
thing in a more formal way.
indent=Relative(+2) are identical.
If you have a lot of data or text to print, and it would normally create super-long, difficult-to-read lines, you can easily wrap it:
say("This is a really long...blah blah blah", wrap=40)
Will automatically wrap the text to the given width
using Python’s standard
Feel free to use indentation and wrapping together.
