Python的进制转换

Posted 2020-10-13 ystwyfe

↓	2进制	8进制	10进制	16进制
2进制	-	bin(int(x, 8))	bin(int(x, 10))	bin(int(x, 16))
8进制	oct(int(x, 2))	-	oct(int(x, 10))	oct(int(x, 16))
10进制	int(x, 2)	int(x, 8)	-	int(x, 16)
16进制	hex(int(x, 2))	hex(int(x, 8))	hex(int(x, 10))	-

 

　Example:

 

number = 10
number_bin = bin(number)
number_oct = oct(number)
number_hex = hex(number)
print("--------------- 十进制转换 -----------------------------")
print(number, "所对应的二进制表示为：", number_bin)
print(number, "所对应的八进制表示为：", number_oct)
print(number, "所对应的十六进制表示为：", number_hex)
print("--------------- 二进制转换 -----------------------------")
print(number_bin, "所对应的十进制表示为：", int(number_bin, 2))
print(number_bin, "所对应的八进制表示为：", oct(int(number_bin, 2)))
print(number_bin, "所对应的十六进制表示为：", hex(int(number_bin, 2)))
print("--------------- 八进制转换 -----------------------------")
print(number_oct, "所对应的十进制表示为：", int(number_oct, 8))
print(number_oct, "所对应的二进制表示为：", bin(int(number_oct, 8)))
print(number_oct, "所对应的十六进制表示为：", hex(int(number_oct, 8)))
print("--------------- 十六进制转换 -----------------------------")
print(number_hex, "所对应的十进制表示为：", int(number_hex, 16))
print(number_hex, "所对应的二进制表示为：", bin(int(number_hex, 16)))
print(number_hex, "所对应的八进制表示为：", oct(int(number_hex, 16)))
