Python tuple method cmp() compares elements of two tuples.
Following is the syntax for cmp() method −
tuple1 − This is the first tuple to be compared
tuple2 − This is the second tuple to be compared
If elements are of the same type, perform the compare and return the result. If elements are different types, check to see if they are numbers.
If numbers, perform numeric coercion if necessary and compare.
If either element is a number, then the other element is "larger" (numbers are "smallest").
Otherwise, types are sorted alphabetically by name.
If we reached the end of one of the tuples, the longer tuple is "larger." If we exhaust both tuples and share the same data, the result is a tie, meaning that 0 is returned.
The following example shows the usage of cmp() method.
#!/usr/bin/python tuple1, tuple2 = (123, 'xyz'), (456, 'abc') print cmp(tuple1, tuple2) print cmp(tuple2, tuple1) tuple3 = tuple2 + (786,); print cmp(tuple2, tuple3)
When we run above program, it produces following result −
-1 1 -1
