Python retrieval string and retrieval number determination function example, python Retrieval

This document describes the Python retrieval string and retrieval number determination functions. We will share this with you for your reference. The details are as follows:

A return string is a string. The read from left to right is exactly the same as the read from right to left. The same is true for the input number.

The python2 code is as follows:

Def huiwen (s): s1 = str (s) if s1 = ''. join (reversed (s1): return True else: return False

Running result:

>>> Huiwen ('abccba') True >>> huiwen ('abc') False >>> huiwen (23432) True >>> huiwen (23432111) False

The above code is usedJoin ()Functions andReversed ()Function, the use of the two is as follows:

Join ()For details about how to use the function, see python str. join ()

Reversed ()For details about how to use the function, see the python built-in function reversed ()
