The problem
Numbers ending with zeros are boring.
They could be enjoyable in your world, however not right here.
Eliminate them. Solely the ending ones.
1450 -> 145
960000 -> 96
1050 -> 105
-1050 -> -105
The answer in Python code
Possibility 1:
def no_boring_zeros(n):
n = str(n)
for i in vary(len(n)-1, 0, -1):
if n[i]=="0":
n = n[:-1:]
else:
return int(n)
return int(n)
Possibility 2:
def no_boring_zeros(n):
attempt:
return int(str(n).rstrip('0'))
besides ValueError:
return 0
Possibility 3:
def no_boring_zeros(n):
return int(str(n).rstrip("0")) if n else n
