python中二進制整數

Given an integer number and we have to find necessary bits to represent it in binary in python.

給定一個整數，我們必須找到必要的位以用python二進制表示它 。

To find necessary bits to represent a number – we use "bit_length()" method of "int" class, it is called with an integer object and returns the total number of bits to require to store/represent an integer number in binary.

為了找到表示數字的必要位，我們使用“ int”類的“ bit_length()”方法 ，將其與整數對象一起調用，并返回以二進制存儲/表示整數所需的位數。

Note: If the value is 0, bit_length() method returns 0.

注意：如果值為0，則bit_length()方法將返回0。

Example:

例：

Input:num = 67 #binary: 1000011# function callprint(num.bit_length())Output:7

Python代碼查找表示整數的位 (Python code to find bits to represent an integer number)

# Python program to find number of bits # necessary to represent an integer in binary# input a number num = int(input("Enter an integer number: "))# total bits to represent number bits = num.bit_length()print("bits required to store ", num, " = ", bits) print("binary value of ", num, " is = ", bin(num))

Output

輸出量

First run: Enter an integer number: 67 bits required to store 67 = 7 binary value of 67 is = 0b1000011Second run: Enter an integer number: 3 bits required to store 3 = 2 binary value of 3 is = 0b11
