The Unicode code point for the degree symbol is 176, so you can use chr(176) to obtain the character corresponding to that code point. We can use the following code block to print the degree symbol in Python. Example Code: print(chr(176)) Output: ° We can also write it along wi...
2.2.2. binding for function cell 和set类似,对于函数也有fset,不过没有fsetq: (fset'a(lambda(x)(+x1)))(a1)=>2 相比value cell,function cell就没有那么多的花样了。一般 symbol 的function cell用于全局函数的 binding,不过这也不是说没有创建临时 binding 的方法。
