python-阿拉伯数字转大写|好友管理系统

1.阿拉伯数字转为大写

chinese_dict = {
    0: '零',1: '壹',2: '贰',3: '叁',4: '肆',5: '伍',6: '陆',7: '柒',8: '捌',9: '玖'
}
unit_list = ['', '拾', '佰', '仟', '万', '拾', '佰', '仟', '亿','拾', '佰', '仟', '兆']
def transform(number):
    if number == 0:
        return '零'
    chinese_number = ''
    number_str = str(number)

    for i, digit in enumerate(number_str):
        digit = int(digit)
        if digit != 0:
            chinese_number += chinese_dict[digit] + unit_list[len(number_str) - i - 1]
        else:
            if chinese_number[-1] != '零' and (i < len(number_str) - 1 and int(number_str[i+1]) != 0):
                chinese_number += chinese_dict[digit]

    return chinese_number

if __name__=="__main__":
    ind = int(input("请输入一个数字：\t"))
    print(transform(ind))

2.好友管理系统

friends=[]
def funFri(inIndex):
    if inIndex==1:
        name=input("请输入要添加的好友名称:\t")
        zeng(name)
    elif inIndex==2:
        name = input("请输入要删除好友姓名:\t")
        shan(name)
        print("好友删除成功")
    elif inIndex==3:
        name = input("请输入要添加备注的好友姓名:\t")
        beizhu=input("请输入要添加的备注:\t")
        addbeizhu(name,beizhu)
    elif inIndex==4:
        cha()
    else:
        inIndex==5
def ifExist(name):
    for i in range(len(friends)):
        if friends[i].get("name") == name:
            return i
    return None
def zeng(name):
    if ifExist(name!=None):
        print("好友名称存在，好友添加失败")
    else:
        friends.append({"name":name})
        print("好友添加成功")
def shan(name):
    ind=ifExist(name)
    if ind!=None:
        friends.pop(ind)
    else:
        print("没有该好友，无需删除")
def addbeizhu(name,beizhu):
    ind=ifExist(name)
    if(ind!=None):
        friends[ind]['beizhu']=beizhu
    else:
        print("没有改好友，添加备注失败")
def cha():
    # print(friends)
    for i in range(len(friends)):

        beizhu=friends[i].get("beizhu")
        if beizhu:
            print(friends[i].get("name") + '\t' + beizhu)
        else:
            print(friends[i].get("name"))

def main():
    print("欢迎使用好友系统")
    print("1. 添加好友\t2. 删除好友\t3. 备注好友\t4. 展示好友\t5. 退出")
    inIndex=int(input("请输入您的选项:\t"))

    while(inIndex!=5):
        funFri(inIndex)
        inIndex = int(input("请输入您的选项:\t"))
if __name__=="__main__":
    main()
