+Pads a string on both sides with the specified character, if it's shorter than the specified length.
+
+- Use `str.ljust()` and `str.rjust()` to pad both sides of the given string.
+- Omit the third argument, `char`, to use the whitespace character as the default padding character.
+
+```py
+from math import floor
+
+def pad(s, length, char = ' '):
+  return s.rjust(floor((len(s) + length)/2), char).ljust(length, char)
+```
+
+```py
+pad('cat', 8) # '  cat   '
+pad('42', 6, '0') # '004200'
+pad('foobar', 3) # 'foobar'
+```
