Python List cmp() Method with example



Hello dear readers! Welcome back to another edition of our tutorial on Python. In this tutorial guide, we are going to be discussing about the Python List cmp() method.

The Python list cmp() method compares elements of two lists.

Syntax

The following below is the syntax for the Python List cmp() method -

cmp(list1,   list2 )


Parameter Details

  • list1- This is the first list to be compared.
  • list2 - The is the second list to be compared.

Return Value

If the elements are of the same type, performs the compare and return the result. If the elements are of different types, then check to see if they are numbers.

  • If numbers, then it performs numeric coercion if need be and compare.
  • If either of the elements is a number, the other element is "larger".
  • Else, the types are sorted alphabetically by name.

If we reach the end of the lists, the longer list is "larger". If we exhaust both lists and share same data, the result is a tie, meaning 0 is returned.

Example

The following below is a simple example -

#!/usr/bin/python

list1, list2 = [123, 'xyz'], [456, 'abc']
print cmp(list1, list2)
print cmp(list2, list1)
list3 = list2 + [786];
print cmp(list2, list3)

Output
Below is the output of the above example -

-1
1
-1
