如果需要在 F 字符串中使用大括号字面值,可以用一个额外的大括号进行转义: >>>spam =42>>>f'This prints the value in spam:{spam}''This prints the value in spam: 42'>>>f'This prints literal curly braces: {{spam}}''This prints literal curly braces: {spam}' 因为您可以将变量名和表达式内...

Alternately, a set can be defined with curly braces ({}): #第二种生成方式,是大括号括起来的对象。 x={<obj>,<obj>,...,<obj>} When a set is defined this way, each<obj>becomes a distinct element of the set, even if it is an iterable. This behavior is similar to that of the....
Sometimes, you start by creating an empty dictionary with an empty pair of curly braces. Then, you start adding new key-value pairs one at a time. Consider the following example where you populate a dictionary with a person’s data: Python >>> person = {} >>> person["first_name"]...
