有了 PyCharm,IDE 就不再是限制。 Cory Althoff CompTIA 软件开发项目高级副总裁以及《The Self-Taught Programmer》的作者 PyCharm 是我最喜欢的 IDE。从漂亮的 UI 到让我的程序员生涯变得更轻松的功能,比如全行代码补全和对 Jupyter Notebook 的支持,我无法想象没有它的生活。我使用 PyCharm 已经十多年了,...

In Python, joining a list of strings involves concatenating the elements of the list into a single string, using a specified delimiter to separate each element. This operation is particularly useful when you need to convert a list of strings into a single string, such as when you want to sa...

reversed()和sorted()同样表示对列表/元组进行倒转和排序,reversed()返回一个倒转后的迭代器(上文例子使用list()函数再将其转换为列表);sorted()返回排好序的新列表。 列表和元组存储方式的差异 前面说了,列表和元组最重要的区别就是,列表是动态的、可变的,而元组是静态的、不可变的。这样的差异,势必会影响两者...
