##Python- Use of backquote a depreciated way as in python 3 for repr() and short way of solving a problem
Print reverse digits of an number. Note, The input is assumed to be a 32-bit signed integer. Your function should return 0 when the reversed integer overflows.
def reverse(x):
number = int(x)
flag = False
if number < 0:
flag = True
#print flag
reversenum = 0
#print abs(number)
while abs(number)>0:
number = abs(number)
remainder = number%10
reversenum = (reversenum*10)+remainder
number = number//10
if (reversenum) > 2**(32-1):
return 0
elif reversenum < 2**(32-1)and flag is True:
return -(reversenum)
else:
return reversenum
###Short way and showing usage of back quote
def reverse(x):
s = cmp(x, 0)
r = int(`s*x`[::-1]) # or int(repr(s*x)[::-1])
return s*r * (r < 2**31)
