A simple equation that contains one variable likex−4−2=0x−4−2=0can be solved using the SymPy'ssolve()function. When only one value is part of the solution, the solution is in the form of a list. The code section below demonstrates SymPy'ssolve()function when an expression ...
1.# Good 3.my_list = [1, 2, 3, 4, 5] 5.my_dict = {'key1': 'value1', 'key2': 'value2'} 7.my_name = "Frank" 我还把我的变量 x的名字改为 my_name。这不是Pycharm建议的,但PEP8建议使用容易理解的变量名。 6. 在处理字典时没有正确使用.key和.values方法 ...

When we reach the point where the problem is as simple as it can get, we begin to piece together the solutions of each of the small problems until the initial problem is solved. Figure 4.2 shows the additions that are performed as list_sum works its way backward through the ...
4.22. The Ordered List Abstract Data Type The structure of an ordered list is a collection of items where each item holds a relative position that is based upon some underlying characteristic of the item. The ordering is typically either ascending or descending and we assume that list items hav...
