Python Program to Find All Numbers which are Odd and Palindromes Between a Range of Numbers
When it is required to find all the numbers that are odd, and are palindromes and lie between a given range of values, and it has been told that recursion can’t be used, then, list comprehension, and ‘%’ operator can be used to achieve the same.
Palindromes are string that are same when they are read in either way- left to right and right to left.
Below is a demonstration for the same −
Example
my_list = []
lower_limit = 5
upper_limit = 189
print("The lower limit is : ")
print(lower_limit)
print("The upper limit is : ")
print(upper_limit)
my_list = [x for x in range(lower_limit,upper_limit+1) if x%2!=0 and str(x)==str(x)[::-1]]
print("The numbers which are odd and palindromes between " + str(lower_limit) + " and " + str(upper_limit) + " are : ")
print(my_list)Output
The lower limit is : 5 The upper limit is : 189 The numbers which are odd and palindromes between 5 and 189 are : [5, 7, 9, 11, 33, 55, 77, 99, 101, 111, 121, 131, 141, 151, 161, 171, 181]
Explanation
- An empty list, a lower limit and an upper limit is defined.
- The upper and lower limit are displayed on the console.
- The values between upper and lower limit are iterated over, and checked to see if it is divisible by 2.
- Then, it is converted to a string, and elements from the end of the string and the string are compared.
- This is assigned to a variable.
- This is displayed as output on the console.
