列表中的子切片元素
Sub-slicing elements in a list
我正在尝试对列表中的元素进行切片，从每个元素中的最少元素中取出两个字符。期望的输出是这样的：
["e","o","ree","ur"]
lst = ["one","two","three","four"]
lst2 = []
for x in lst:
lst2.append((lst[:2]))
print(lst2)
# this is not what I want but is resulting from this code:
['one', 'two'], ['one', 'two'], ['one', 'two'], ['one', 'two']]
lst = ["one","two","three","four"]
lst2 = [x[2:] for x in lst]
print(lst2) # ['e', 'o', 'ree', 'ur']
