How can I find out the number of Bytes a certain integer number takes up to store? E.g. for hexadecimal x00 – xff (or decimal 0 – 255 = binary 0000 0000 – 1111 1111) I’m looking to get 1 (Byte), hexadecimal x100 – xffff (or decimal 256 – 65535 = binary 0000 0001 0000 0000 &…

Maximum and Minimum values for ints
How do I represent minimum and maximum values for integers in Python? In Java, we have Integer.MIN_VALUE and Integer.MAX_VALUE. See also: What is the maximum float in Python?. Answer Python 3 In Python 3, this question doesn’t apply. The plain int type is unbounded. However, you might actually be lookin…
Why does integer division yield a float instead of another integer?
Consider this division in Python 3: Is this intended? I strongly remember earlier versions returning int/int = int. What should I do? Is there a new division operator or must I always cast? In 2.x, the behaviour was indeed reversed; see How can I force division to be floating point? Division keeps rounding do…
How can I force division to be floating point? Division keeps rounding down to 0?
I have two integer values a and b, but I need their ratio in floating point. I know that a < b and I want to calculate a / b, so if I use integer division I’ll always get 0 with a remainder of a. How can I force c to be a floating point number in Python 2 in
How can I check if a string represents an int, without using try/except?
Is there any way to tell whether a string represents an integer (e.g., ‘3’, ‘-17’ but not ‘3.14’ or ‘asfasfas’) Without using a try/except mechanism? Answer If you’re really just annoyed at using try/excepts all over the place, please just write a helper f…
How do I parse a string to a float or int?
How can I convert a str to float? How can I convert a str to int? For the reverse, see Convert integer to string in Python and Converting a float to a string without rounding it. Please instead use How can I read inputs as numbers? to close duplicate questions where OP received a string from user input and im…
