如何修复 int 在 python 中不可迭代？

Question

我以十六进制输入 pesan。例如 e = 5、n = 221 和 pesan = 1e。然后 pesan 将转换为十进制并解密。结果（十进制）将再次转换为十六进制。但我得到了错误

TypeError: 'int' object is not iterable.

如何解决？这是代码

def mod(x,y):
    if (x < y):
        return x
    else:
        c = x % y
        return c

def hex_to_decimal(hex_str):
    decimal_number = int(hex_str, 16)
    return decimal_number
                 
def decimal_to_hex(decimal_str):
    decimal_number = int(decimal_str, 10)
    hex_number = hex(decimal_number)[2:]
    return hex_number

def decrypt(m):
    plainDecimal=[]
    for i in m:
        cipherElement=mod(int(i)**e,n)
        plainDecimal.append(cipherElement)
    return plainDecimal

e = int(input('Input e: '))
n = int(input('Input n: '))
pesan = input('Input message: ' )
decimalp = hex_to_decimal(pesan) #Convert hex to decimal
plain = decrypt(decimalp)
ListToStr2 = ''.join([str(x) for x in plain])
decimal1 = decimal_to_hex(ListToStr2) #Convert decimal to hex
print("Dekripsi Tanda Tangan Digital (Heksadesimal): ", decimal1)

我已经解决了这个问题。这是代码

def mod(x,y):
    if (x < y):
        return x
    else:
        c = x % y
        return c

def hex_to_decimal(hex_str):
    decimal_number = int(hex_str, 16)
    return decimal_number
                 
def decimal_to_hex(decimal_str):
    decimal_number = int(decimal_str, 10)
    hex_number = hex(decimal_number)[2:]
    return hex_number

def decrypt(m):
    m_str = str(m)
    decimalList =[int(m_str)]
    plainDecimal=[]
    for i in decimalList:
        cipherElement = mod(int(i)**e,n)
        plainDecimal.append(cipherElement)
    return plainDecimal

e = int(input('Input e: '))
n = int(input('Input n: '))
pesan = input('Input message: ' )
decimalp = str(hex_to_decimal(pesan)) #Convert hex to decimal
plain = decrypt(decimalp)
ListToStr2 = ''.join([str(x) for x in plain])
decimal1 = decimal_to_hex(ListToStr2) #Convert decimal to hex
print("Dekripsi Tanda Tangan Digital (Heksadesimal): ", decimal1)

在代码中，您给出的 decimalp 值是一个 int，我现在使用 str() 函数将 decimalp 值更改为字符串。代码现在应该可以完美运行了。修正后的代码如下；

def mod(x,y):
    if (x < y):
        return x
    else:
        c = x % y
        return c

def hex_to_decimal(hex_str):
    decimal_number = int(hex_str, 16)
    return decimal_number
                 
def decimal_to_hex(decimal_str):
    decimal_number = int(decimal_str, 10)
    hex_number = hex(decimal_number)[2:]
    return hex_number

def decrypt(m):
    plainDecimal=[]
    for i in m:
        cipherElement=mod(int(i)**e,n)
        plainDecimal.append(cipherElement)
    return plainDecimal

e = int(input('Input e: '))
n = int(input('Input n: '))
pesan = input('Input message: ' )
decimalp = str(hex_to_decimal(pesan)) #Convert hex to decimal
plain = decrypt(decimalp)
ListToStr2 = ''.join([str(x) for x in plain])
decimal1 = decimal_to_hex(ListToStr2) #Convert decimal to hex
print("Dekripsi Tanda Tangan Digital (Heksadesimal): ", decimal1)
