python - 在 Python 中对字符串列表进行排序

Question

<分区>

Answer 1

使用不区分大小写的比较:

>>> sorted(['Dog', 'bicycle', 'cow', 'doctor', 'Car', 'Boat',
        'apple', 'Airplane'], key=str.lower)
['Airplane', 'apple', 'bicycle', 'Boat', 'Car', 'cow', 'doctor', 'Dog']

这实际上是 python wiki about sorting 上建议的方式:

Starting with Python 2.4, both list.sort() and sorted() added a key parameter to specify a function to be called on each list element prior to making comparisons.

For example, here's a case-insensitive string comparison:

>>> sorted("This is a test string from Andrew".split(), key=str.lower)
['a', 'Andrew', 'from', 'is', 'string', 'test', 'This']
