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 – 1111 1111 1111

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 looking for information about the current interpreter’s word size, which will
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 down to 0? for the opposite, 2.x-specific
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 function: It’s going to be WAY more code to exactly cover all the strings that Python considers
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 immediately
