在Python中以二进制格式输入数字

Syntax to convert binary value to an integer (decimal format),

将二进制值转换为整数(十进制格式)的语法，

int(bin_value, 2)

Here,

这里，

• bin_value should contain the valid binary value

  bin_value应该包含有效的二进制值

• 2 is the base value of the binary number system

  2是二进制数系统的基值

Note: bin_value must contain only binary digits (0 and 1), if it contains other than these digits a "ValueError" will return.

注意 ： bin_value必须仅包含二进制数字(0和1)，如果它不包含这些数字，则将返回“ ValueError” 。

将给定的二进制值转换为整数(十进制)的程序 (Program to convert given binary value to integer (decimal))

# function to convert given binary Value # to an integer (decimal number) def BinToDec(value):try:return int(value, 2)except ValueError:return "Invalid binary Value"# Main code input1 = "11110000" input2 = "10101010" input3 = "11111111" input4 = "000000" input5 = "012"print(input1, "as decimal: ", BinToDec(input1)) print(input2, "as decimal: ", BinToDec(input2)) print(input3, "as decimal: ", BinToDec(input3)) print(input4, "as decimal: ", BinToDec(input4)) print(input5, "as decimal: ", BinToDec(input5))

Output

输出量

11110000 as decimal: 240 10101010 as decimal: 170 11111111 as decimal: 255 000000 as decimal: 0 012 as decimal: Invalid binary Value

Now, we are going to implement the program – that will take input the number as an binary number and printing it in the decimal format.

现在，我们将实现该程序–该程序将输入数字作为二进制数字并以十进制格式打印。

程序以二进制格式输入数字 (Program to input a number in binary format)

# input number in binary format and # converting it into decimal formattry:num = int(input("Input binary value: "), 2)print("num (decimal format):", num)print("num (binary format):", bin(num)) except ValueError:print("Please input only binary value...")

Output

输出量

RUN 1: Input binary value: 11110000 num (decimal format): 240 num (binary format): 0b11110000RUN 2: Input binary value: 101010101010 num (decimal format): 2730 num (binary format): 0b101010101010RUN 3: Input binary value: 1111111111111111 num (decimal format): 65535 num (binary format): 0b1111111111111111RUN 4: Input binary value: 0000000 num (decimal format): 0 num (binary format): 0b0RUN 5: Input binary value: 012 Please input only binary value...
