Python 各种进制转换

def binary_to_decimal(binary_number):#2进制转换成10进制return int(binary_number, 2)
def hex_to_decimal(binary_number):#hexadecimal #16进制转换成10进制return int(binary_number, 16)
def octal_to_decimal(binary_number):#8进制转换成10进制return int(binary_number, 16)def dec2hex(dec_num):#10进制转换成16进制return hex(dec_num)
def dec2hex_f(dec_num,formatl_num):#带输出位宽，不足的左边补0 return hex(dec_num)[2:].upper().zfill(formatl_num)
def dec2bin(dec_num):#10进制转换成2进制return bin(dec_num)
def dec2bin_f(dec_num,formatl_num):#带输出位宽，不足的左边补0return bin(dec_num)[2:].upper().zfill(formatl_num)
def dec2oct(dec_num):#10进制转换成8进制return oct(dec_num)
def dec2oct_f(dec_num,formatl_num):#带输出位宽，不足的左边补0return oct(dec_num)[2:].upper().zfill(formatl_num)

测试代码

print("Binary number:", binary_number)
print("Decimal number:", decimal_number)
print("Decimal number:", binary_to_decimal("0101"))
print("Decimal number:", hex_to_decimal("000a"))
print("Decimal number:", dec2hex(10))
print("Decimal number:", dec2hex_f(10,4))
print("Decimal number:", dec2bin(10))
print("Decimal number:", dec2bin_f(10,4))
print("Decimal number:", dec2oct(10))
print("Decimal number:", dec2oct_f(10,4))
