28
+
29
+ Returns an iterator over the strings resulting from brace expansion
30
+ of pattern. This function implements Brace Expansion as described in
31
+ bash(1), with the following limitations:
32
+
33
+ * A pattern containing unbalanced braces will raise an
34
+ UnbalancedBracesError exception. In bash, unbalanced braces will either
35
+ be partly expanded or ignored.
36
+
37
+ * A mixed-case character range like '{Z..a}' or '{a..Z}' will not
38
+ include the characters '[]^_`' between 'Z' and 'a'.
39
+
40
+ When escape is True (the default), characters in pattern can be
41
+ prefixed with a backslash to cause them not to be interpreted as
42
+ special characters for brace expansion (such as '{', '}', ',').
43
+ To pass through a a literal backslash, double it ('\\\\').
44
+
45
+ When escape is False, backslashes in pattern have no special
46
+ meaning and will be preserved in the output.
