问题描述
我想做类似deltax=symbols(",,\delta x")但这似乎给出了一个元组而不是多字符符号.甚至有可能吗?我应该补充一点，我正在使用 Jupyter.
I would like to do something like deltax=symbols(",,\delta x")But this seems to give a tuple not a multicharacter symbol. Is it even possible?I should add that I am using Jupyter.
推荐答案
symbols 函数很方便，它允许我们一次创建多个符号，例如 a, b, c= symbol("a,b,c") 或 a, b, c = symbols("abc")，或 syms = symbols("a1:6").缺点是我们不能使用它来创建名称中带有逗号(或空格或冒号)的符号.相反，必须直接使用 Symbol 类的构造函数:
The function symbols is convenient in that it allows us to create several symbols at once, like a, b, c = symbols("a,b,c") or a, b, c = symbols("a b c"), or syms = symbols("a1:6"). The downside is that we can't use it to create a symbol with a comma (or a space, or a colon) in its name. Instead, the constructor of Symbol class has to be used directly:
deltax = Symbol(",,\delta x")
