By converting the original list back to a set, you eliminate duplicate elements, thereby reducing the number of membership checks needed. This approach is particularly useful when you need to perform multiple membership tests on an unchanging list....

# Check for existence in a list with "in" 1 in li # => True # Examine the length with "len()" len(li) # => 6 tuple tuple和list非常接近,tuple通过()初始化。和list不同,tuple是不可变对象。也就是说tuple一旦生成不可以改变。如果我们修改tuple,会引发TypeError异常。
last_element=my_list.pop() 输出: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 'pineapple' 6、列表推导式 列表推导式是for循环的简易形式,可以在一行代码里创建一个新列表,同时能通过if语句进行判断筛选 代码语言:javascript 代码运行次数:0

冗余数据处理Duplicate Data DataFrame的duplicated方法返回一个布尔型Series,表示各行是否重复行。而 drop_duplicates方法,它用于返回一个移除了重复行的DataFrame data.drop_duplicates(inplace=True) 或者data = data.drop_duplicates() 只对某一列有重复则删除:df.drop_duplicates(subset=0, inplace=True)...
5. Duplicate Items with * 6. Compare Tuples works much like list comparisons. 7. Tuple iteration is like iteration of other types 8. Tuple can't be modified(As you saw just before, you can concatenate (combine) tuples to make a new one, as you can with strings) Lists: Unlike string...
