Slicing strings

Question

In python, I want to slice strings in a list in such a way that first few characters from that list must be removed/spliced out.

a=['hello', 'things', 'becoming', 'expensive']

如何从列表中的每个字符串中删除前两个字符以获取输出

['llo', 'ings', 'coming', 'pensive']

Answer 1

a=['hello', 'things', 'becoming', 'expensive']
b = []

for word in a:
    b.append(word[2:])


print(b)

结果是：

['llo', 'ings', 'coming', 'pensive']

这段：

word[2:] 

是说从索引 2 开始并将所有内容返回到它的右侧。索引从 0 开始，所以前 2 个字母被忽略
