【python基础知识】列表去重的 多种方法

1）set()函数去重

list1=[1,2,3,2,4,3,5,4,2,2,5,6]
list2=list(set(list1))
print(list2)

2)利用for循环

list3=[1,2,3,4,3,2,3,4,5,9]
for i in list3:
    if list3.count(i)>1:
        list3.remove(1)
print(i)

3)利用列表循环判断是否重复

list4=[1,2,3,2,5,4,6]
ww=[]
for i in list4:
    if i not in ww:
        ww.appence(ww)
print(ww)
