python实现整数的二进制循环移位

# left circular shift
 
#int_value是输入的整数，k是位移的位数，bit是整数对应二进制的位数
 
def circular_shift_left (int_value,k,bit = 8): 
 bit_string = '{:0%db}' % bit
 bin_value = bit_string.format(int_value) # 8 bit binary
 bin_value = bin_value[k:] + bin_value[:k]
 int_value = int(bin_value,2) 
 return int_value
 
 
# right circular shift
 
def circular_shift_right (int_value,k,bit = 8): 
 bit_string = '{:0%db}' % bit 
 bin_value = bit_string.format(int_value) # 8 bit binary 
 bin_value = bin_value[-k:] + bin_value[:-k] 
 int_value = int(bin_value,2) 
 return int_value
 
 
if __name__ == "__main__": 
 A=1 
 B=circular_shift_right(A, 1, 8)
 print(A,"右循环位移1位的结果是",B)
 
 C = 128
 
 D =circular_shift_left(C,1,8)
 
 print(C, "左循环位移1位的结果是", D)
