The language comprising of these sequences is known as binary language. The different permutations of 0s and 1s give us different sequences which in turn are used to represent different letters, numbers, and special characters in the memory. The only thing a machine or a computer can understand is two signals: power off and power on, These signals are represented using two numbers, 0 and 1 respectively. Return ((num = 0) and '0') or (baseN(num // b, b).Computers have a different language and they cannot understand words and sentiments as we all do. Return dec2bin(hex2dec(string_num.upper()))

If x is not a Python int object, it has to define an _index_() method that returns an integer.īin()、oct()、hex()的返回值均为字符串，且分别带有0b、0o、0x前缀。 Base 0 means to interpret exactly as a code literal, so that the actual base is 2, 8, 10, or 16, and so that int('010', 0) is not legal, while int('010') is, as well as int('010', 8).Ĭonvert an integer number to a hexadecimal string. Base-2, -8, and -16 literals can be optionally prefixed with 0b/0B, 0o/0O, or 0x/0X, as with integer literals in code.

A base-n literal consists of the digits 0 to n-1, with ‘a' to ‘z' (or ‘A' to ‘Z') having values 10 to 35. A string must be a base-radix integer literal optionally preceded by ‘+' or ‘-‘ (with no space in between) and optionally surrounded by whitespace. Conversion of floating point numbers to integers truncates towards zero. If a number is given, return number._int_(). If x is not a Python int object, it has to define an _index_() method that returns an integer.Ĭonvert a number or string to an integer. If x is not a Python int object, it has to define an _index_() method that returns an integer.Ĭonvert an integer number to an octal string.
