# 1：生成一个由1-10的平方组成的列表
number = [i * i for i in range(1, 11)]
print(number)

# 2：字符串s1=‘ABC’，字符串s2=‘123’，要求：生成序列 A1 A2 A3 B1 B2 B3 C1 C2 C3
str1 = ['A' + str(i) for i in range(1, 4)]
str2 = ['B' + str(i) for i in range(1, 4)]
str3 = ['C' + str(i) for i in range(1, 4)]
print(str1)
print(str2)
print(str3)

# 3：将3×3的矩阵alist1转换成一个列表，且使该列表中包含偶数
alist1 = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
mylist = []
# list=[i for i in alist1[0][:] for y in alist1[1][:] for j in alist1[2][:]]
for i in range(3):
    for i in alist1[i]:
        if i % 2 == 0:
            mylist.append(i)
print(mylist)

# 4：取出所有带a的列表
list1 = ['52pojie', 'OVVO', 'asd', 'sdf', 'freg', 'sfag', 'refv', 'aser', 'sdfr']
word = [i for i in list1 if 'a' in i]
print(word)
