我在本章的第二段中添加了一个新的引语和一些文字,以解释“Pythonic”的概念——这在第一版中只在最后讨论过。 “格式化显示”已更新以提及在 Python 3.6 中引入的 f-strings。这是一个小改变,因为 f-strings 支持与format()内置和str.format()方法相同的格式迷你语言,因此以前实现的__format__方法可以与 f...

The second limitation of key is that the function used with key must be able to handle all the values in the iterable.Here, you have a list of numbers represented as strings to be used in sorted(), and key is going to attempt to convert them to numbers using int:...
Python 取list 差集 python set取差集 交集(intersection) example: valid = set(['yellow', 'red', 'blue', 'green', 'black']) input_set = set(['red', 'brown']) print(input_set.intersection(valid)) ### 输出:set(['red']) # 方法一:...
The preceding code trusts that everything after the colon (:) is a temperature. The string is split at:, which produces a list of two items. Using[-1]on the list returns the last item, which is the temperature in this example.
