hex_string='A1B2C3'decimal_number=int(hex_string,16) 1. 2. 解释一下代码的意思: hex_string变量存储了十六进制字符串。 int()函数将hex_string转换为十进制数,第二个参数16指明了hex_string是一个十六进制数。 步骤二:将十进制数转换为字节串形式 在Python中,我们可以使用内置函数to_bytes()将十进制数...

In this example, we will be using the literal evaluation function, which helps us to predict the base and converts the number string to its decimal number format. The literal_eval() function is available in ast module. Let us look at the example for understanding the concept in detail. #...

在Python中,可以使用int()、bin()、oct()和hex()函数来实现进制转换。 1. int()函数:将其他进制的数字转换为十进制。 示例代码: “`python num = “1010” # 二进制数 decimal_num = int(num, 2) print(decimal_num) # 输出:10 “` 在int()函数中,第一个参数是要转换的数字,第二个参数是表示该...
In this example,str()is smart enough to interpret the binary literal and convert it to a decimal string. If you want a string to represent an integer in another number system, then you use a formatted string, such as anf-string(in Python 3.6+), and anoptionthat specifies the base: ...
