参考伪代码

Write "Enter the new base"                                        # 打印进入新进制
Read newBase                                                      # 输入新的进制
Write "Enter the number to be converted"                          # 输入“要被转化的数”文字提示
Read decimalNumber                                                # 输入十进制数
Set quotient to 1						  # 将商设置为1
WHILE (quotient is not zero)					  # 当商不是零
    Set quotient to decimalNumber DIV newBase		          # 将商设置为十进制数DIV新基数
    Set remainder to decimalNumber REM newBase			  # 将余数设置为新基数的十进制数
    Make the remainder the next digit to the left in the answer	  # 将余数作为答案左边的下一个数字
    Set decimalNumber to quotient				  # 将十进制数设置为商
Write "The answer is "
Write answer

十进制转换为二进制或八进制代码

def baseconvert_dectobinoroct():
    list_empty = []
    a = int(input("请输入一个自然数:"))
    b = int(input("请输入转化的进制(输入1至9中的一个进制基数):"))
    remainder = a % b                   
    quotient = (a - remainder) / b      
    while quotient != 0:
        list_empty.append(int(remainder))
        a = (a - remainder) / b
        remainder = a % b
        quotient = (a - remainder) / b
    else:
        list_empty.append(int(remainder))
        list_answer = list_empty[::-1]
    d = ''
    for i in range(len(list_answer)):
        c = list_answer[i]
        d = str(d) + str(c)
    print(d)

十进制转换为十六进制代码

def baseconvert_dectohex():
    dict1 = {"0": 0, "1": 1, "2": 2, "3": 3,
             "4": 4, "5": 5, "6": 6, "7": 7,
             "8": 8, "9": 9, "10": 'A', "11": 'B',
             "12": 'C', "13": 'D', "14": 'E', "15": 'F'}
    list_empty = []
    a = int(input("请输入一个自然数:"))
    b = 16
    remainder = a % b  # 余数
    quotient = (a - remainder) / b  # 商
    while quotient != 0:
        list_empty.append(dict1[str(int(remainder))])
        a = (a - remainder) / b
        remainder = a % b
        quotient = (a - remainder) / b
    else:
        list_empty.append(dict1[str(int(remainder))])
        list_answer = list_empty[::-1]

        c = list_answer[i]
        d = str(d) + str(c)
    print(d)
