from functools import reduce
def is_palindrome(n):
    l = list(str(n)) #['1','0' ]
    l.reverse() # ['0','1'] #
    # print(l.reverse())
    # 1*10+0 = 10
    num = reduce(lambda x,y:int(x) * 10 + int(y),l)
    return num == n
a= is_palindrome('10')
print(a)
output = filter(is_palindrome,range(1,1000))
print('1~1000:',list(output))

Output:

False
