[英]How to remove the same words from two lists?
I have two lists that I want to remove the same words from the lists.我有两个列表,我想从列表中删除相同的单词。 I use this code but it doesn't work:我使用此代码,但它不起作用:
a = ['go ing', 'watch TV', 'ice cream', 'sit ting', 'note book']
b = ['go ing', 'watching TV', 'ice cream', 'sit ing', 'notebook']
if a[i] == b[i]:
try:
a.remove(i)
b.remove(i)
except:
pass
My desired output is a = ['watch TV', 'sit ting', 'note book']
.我想要的 output 是a = ['watch TV', 'sit ting', 'note book']
。 Could anyone help me?有人可以帮我吗?
First of all your answer seems unclear to me, but I guess you want to do this首先你的答案对我来说似乎不清楚,但我想你想这样做
a = ['go ing','watch TV', 'ice cream','sit ting','note book']
b = ['go ing','watching TV','ice cream','sit ing','notebook']
set(a).intersection(set(b))
>>> {'go ing', 'ice cream'}
set(a).difference(set(b))
>>> {'sit ting', 'watch TV', 'note book'}
You can use Set
to perform operations like Difference, Intersection, Union, Symmetric Difference, etc.您可以使用Set
执行差异、交集、并集、对称差异等操作。
