使用分片分配:
my_list[bounds[0]:bounds[1] + 1] = ['foo'] * ((bounds[1] + 1) - bounds[0])
或使用局部变量+ 1
仅添加一次:
lower, upper = bounds
upper += 1
my_list[lower:upper] = ['foo'] * (upper - lower)
您可能希望将上限存储为非包含性,以便更好地使用python并避免所有+ 1
计数。
演示:
>>> my_list = range(10)
>>> bounds = (2, 5)
>>> my_list[bounds[0]:bounds[1] + 1] = ['foo'] * ((bounds[1] + 1) - bounds[0])
>>> my_list
[0, 1, 'foo', 'foo', 'foo', 'foo', 6, 7, 8, 9]
