# -------------------------第一题---------------------------#
number = input('请输入一个整数：')
if (int(number)%7 == 0) | (number.find('7') != -1):
    print('该数与7相关')
else:
    print('该数与7无关')
    

# -------------------------第二题---------------------------#
id = input('请输入身份证号码：')
if len(id) == 18:
    birthday = id[6:14]
    print('你的出生日期是：',birthday)
elif len(id) == 15:
    birthday = '19' + id[6:12]
    print('你的出生日期是：',birthday)
else:
    print('请重新输入身份证号码！')


# -------------------------第三题---------------------------#
id = input('请输入身份证号码：')
if len(id) == 18:
    if int(id[-2]) % 2 == 0:
        print('女')
    else:
        print('男')

    print('请重新输入身份证号码！')


# -------------------------第四题---------------------------#
list6 = [1,5,2,8,10,13,17,4,6]
## 方法一：
result = []
for i in list6:
    result.append(i**2+1)
print(result)

## 方法二：
result = [i**2+1 for i in list6]
print(result)


# -------------------------第五题---------------------------#
list7 = ['one','two','three','four','five','six','seven','eight','nine']
## 方法一：
result = []
for i in list7:
    if i.find('e') != -1:
        new_i = i.replace(i[:],'^-^')
        result.append(new_i)
    else:
        result.append(i)
print(result)

## 方法二：
result = [i for i in list7 if i.find('e')!=-1]
print(result)


#-------------------------第六题---------------------------#
# 同第四题


# -------------------------第七题---------------------------#
list8 = ['A','C','A','C','B','C','A','A','B','C']
dict = {}
for i in set(list8):
    dict[i] = list8.count(i)
print(dict)


# -------------------------第八题-----------------------------#
n = 1
s = 0
while s<=1000:
    s += 3*n+5
    n += 1
    print(n,'-->',s)


# --------------------------第九题-----------------------------#
