我一直在获取错误对象类型int没有len(),不确定原因。我刚刚了解了len函数,因此非常感谢为什么这样做。
bits=int(input("enter an 8-bit binary number"))
for i in range (0,8):
if len(bits) >8 or len(bits) <8:
print("must enter an 8 bit number")
答案 0 :(得分:0)
那应该很容易,因为python的“ int”接受了告诉它的“ base”参数 使用哪个数字基数
strbin = input('enter bin value\n')
converted = int(strbin,base=2)
print('base 2 converted to base 10 is: ', converted)
答案 1 :(得分:0)
您收到该错误是因为您使用input
读取了一个字符串,但立即将其转换为int:
bits=int(input("enter an 8-bit binary number"))
--- there!
诸如"00110011"
之类的输入将作为十进制值bits
存储在110011
中,而没有前导零。正如错误所言,int
没有len
。
将演员表移至int
,以使该部分正常工作。但是,您的(原始)代码中还有很多错误–我希望我能全部解决。 (原谅感叹号,但您的所有错误都应至少引起一个错误。)
您的原始代码是
bits=int(input("enter an 8-bit binary number"))
for i in range (0,8):
if bits >8 and bits <8:
print("must enter an 8 bit number")
if input >1:
print("must enter a 1 or 0")
else:
rem=bits%10
sum=((2**i)*rem)
bits = int(bits/10)
print(sum)
调整为
bits=input("enter an 8-bit binary number")
sum = 0 # initialize variables first!
if len(bits) != 8: # test before the loop!
print("must enter an 8 bit number")
else:
for i in range (8): # default start is already '0'!
# if i > 1: # not 'input'! also, i is not the input!
if bits[i] < '0' or bits[i] > '1': # better also test for '0'
print("must enter a 1 or 0")
# else: only add when the input value is '1'
elif bits[i] == '1':
# rem = bits%10 # you are not dealing with a decimal value!
# sum = ((2**i)*rem) # ADD the previous value!
sum += 2**i
# bits = int(bits/10) # again, this is for a decimal input
# mind your indentation, this does NOT go inside the loop
print(sum)
