Write a Python program to remove duplicate words from a given list of strings. Sample Solution: Python Code: # Define a function 'unique_list' that removes duplicates from a listdefunique_list(l):# Create an empty list 'temp' to store unique elementstemp=[]# Iterate through the elements ...
借用集合(set)剔除list中的重复项(duplicates) 获得两个list的并集 获得两个list的交集 获得后者相对于前者的补集 获得两个list的差集 将多行string变为一行,用空格“ ”分隔 将string中的多个空格删减到1个 只保留string中的字母元素 dictionary操作 .update() 用zip()创建dictionary 获取dict1的key 获取dict1的...

只写一个:,表示全部获取,可以使用del删除指定位置的元素,或者可以使用remove方法。 # Make a one layer deep copy using slices li2 = li[:] # => li2 = [1, 2, 4, 3] but (li2 is li) will result in false. # Remove arbitrary elements from a list with "del" ...
