在python和selenium中删除重复项

Question

longItem = ["Hey there how are you? \n Whats up \n Hi \n Hey there how are you? Whats up \n Wow"]

输出应为：

^{pr2}$

如果你遇到这样的问题怎么解决？ 我知道你在想为什么它只是列表中的一个元素为什么不把它们分开？在

我有一个具体的问题，正是这样，我迷失了，不知道如何解决它

Answer 1

像那样的？在

items = []
for long_item in longItem:
    for item in long_item.split(" \n "):
        if item not in items:
            items.append(item)
print(items)

输出：

^{pr2}$

Answer 2

如果我没听错，你需要这样的东西吗？在

longItem = ["..."] #your item
longItemStr = "".join(longItem).replace('\n ', '\n') # make a string out of list
shortl = longItemStr.partition('\n') # define the phrase length
longItemStr = longItemStr[:len(shortl[0])] # cut other copies
print(longItemStr)

输出结果很简单：

^{pr2}$

更新

是的，这是完全不同的任务：） 试试这个：

s = ['''...''' ] #your data
ss = ''.join(s) #make string
ss = ss.split('\n') #split each element to list
print(set(ss)) #print set with unique data 

更新2

要打印所有唯一元素，请使用：

z = [[i] for i in set(ss)] #make a list for each element in set
for i in range(len(z)): #use for-loop to print them out
    u = ''.join(z[i])
    u = u[:-9] #delete last 9 characters ([CHANGE] thing)
    print(u)

输出为：
