Get last digit of int python
WebFor large numbers (greater than 30 digits in length), use the string domain: def sum_digits_str_fast (n): d = str (n) return sum (int (s) * d.count (s) for s in "123456789") There is also a narrow window for numbers between 20 and 30 digits in length where sum (map (int, str (n))) is fastest. WebMar 28, 2013 · 1 I am writing a Python script that will take an IP address in CIDR format (ie. 1.1.1.0/32 or 10.0.0.1/24) and split the IP into three parts: the first three octets (1.1.1), the last octet (0) and the Subnet mask (32). The IP will be of variable length so I don't know if I can use some sort of string character counter. Any ideas? Thanks python
