Python: Check whether a given integer is a palindrome or not
Python Basic - 1: Exercise-72 with Solution
Write a Python program to check whether a given integer is a palindrome or not.
Note: An integer is a palindrome when it reads the same backward as forward. Negative numbers are not palindromic.
Sample Solution:
Python Code:
def is_Palindrome(n):
return str(n) == str(n)[::-1]
print(is_Palindrome(100))
print(is_Palindrome(252))
print(is_Palindrome(-838))
Sample Output:
False True False

Python: Tips of the Day
Iterating over dictionaries using 'for' loops:
I am a bit puzzled by the following code: d = {'x': 1, 'y': 2, 'z': 3} for key in d: print key, 'corresponds to', d[key] What I don't understand is the key portion. How does Python recognize ...
key is just a variable name.
for key in d:
For Python 3.x:
for key, value in d.items():
For Python 2.x:
for key, value in d.iteritems():
To test for yourself, change the word key to poop.
In Python 3.x, iteritems() was replaced with simply items(), which returns a set-like view backed by the dict, like iteritems() but even better. This is also available in 2.7 as viewitems().
The operation items() will work for both 2 and 3, but in 2 it will return a list of the dictionary's (key, value) pairs, which will not reflect changes to the dict that happen after the items() call. If you want the 2.x behavior in 3.x, you can call list(d.items()).
