以下是Python中常见的不可变类型:整数(Integer) 和浮点数(Float),布尔值(Boolean),字符串(String),元组(Tuple)可变类型是指可以在原地修改的对象,即可以改变其值或状态。当对可变类型的对象进行修改时,不会创建新的对象,而是直接修改原始对象。在修改后,对象的身份标识(即内存地址)保持不变。
在交互式 Shell 中输入以下内容: >>>name ='Al'>>>age =4000>>>f'My name is{name}. Next year I will be{age +1}.''My name is Al. Next year I will be 4001.' 记得包括f前缀;否则,大括号及其内容将成为字符串值的一部分: >>>'My name is {name}. Next year I will be {age + 1...
【Python】归并排序 在排序算法的浩瀚星空中,快速排序以其惊人的平均速度和原地排序的特性,常常占据着耀眼的主导地位。然而,在算法的殿堂里,存在着另一位同样伟大、但在某些方面更为可靠和优雅的巨匠——归并排序(Merge Sort)。它不像快速排序那样依赖精巧的轴心选择和概率性的性能保证,而是以一种近乎确定性的、稳健...

Assigning a string to a variable is done with the variable name followed by an equal sign and the string: Example a ="Hello" print(a) Try it Yourself » Multiline Strings You can assign a multiline string to a variable by using three quotes: ...

Here, say_hello() and be_awesome() are regular functions that expect a name given as a string. The greet_bob() function, however, expects a function as its argument. You can, for example, pass it the say_hello() or the be_awesome() function....
