Python的早期练习题-2

练习

1、- 使用列表推导式找出单词长度大于n的单词

ls = ["google","apple","hello","battle"]
n = 5

for item in ls:
    if len(item) > n:
        print(item)

google
battle

2、- 使用列表推导式寻找两个列表中的相同元素

ls1 = ["google","apple","hello","battle"]
ls2 = ["gooogle","dpple","hello","baattle"]

for item1 in ls1:
    for item2 in ls2:
        if item1 == item2 :
            print(item1)

hello

ls1 = ["google","apple","hello","battle"]
ls2 = ["gooogle","dpple","hello","baattle"]

[a  for a in ls1 for b in ls2 if a == b] 

['hello']

3、- 去除一个列表中相领且重复的元素。

ls =
