Python List cmp() Method
The method cmp() compares elements of two lists.
Following is the syntax for cmp() method
list1 -- This is the first list to be compared.
list2 -- This is the second list 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 lists, the longer list is "larger." If we exhaust both lists 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 list1, list2 = [123, 'xyz'], [456, 'abc'] print cmp(list1, list2); print cmp(list2, list1); list3 = list2 + ; print cmp(list2, list3)
Let us compile and run the above program, this will produce the following result:
-1 1 -1
