练习题总结

一 下面列表：

a = [1,2,3,4,5,333,11,44]

输出下面的结果：

[4,5,333]

a = [1,2,3,4,5,333,11,44]
print(a[3:6])

二 有下面2个列表

a = [1,2,3]
b = [4,5,6]

用2个方法输出下面结果：

[1,2,3,4,5,6]

a = [1,2,3]
b = [4,5,6]
print(a+b)#第一种
c=[]
for i in a:
    c.append(i)
for j in b:
    c.append(j)
print(c)#第二种

三 有下面2个列表：

a = [1,99,33,44,55,22]

输出结果:

1：[1,2,99,33,44,55,22,(11,33,54)]

2: [1,2,99,33,101,44,55,22]

a = [1,99,33,44,55,22]
b = (11,33,54)
a.insert(1,2)
a.append(b)
print(a)#(1)

a = [1,99,33,44,55,22]
b = (11,33,54)
a.insert(1,2)
a.insert(4,101)
print(a)

四：用列表推导式生成100内的大于20的偶数

a = []
for i in range(100):
    if i > 20:
        if i % 2 == 0:
            a.append(i)
print(a)
