无需使用数字键盘即可完成此操作的一种方法是简单地打印字符,然后将其复制/粘贴为标签。 >>> print("lower case delta: \u03B4") lower case delta: δ >>> δ = 42 # copy the lower case delta symbol and paste it to use it as a label >>> δδ = δ ** 2 # paste it twice to define another label. >>> δ # at this point, they are just normal labels... 42 >>> δδ 1764 >>> δabc = 737 # using paste, it's just another character in a label >>> δ123 = 456 >>> δabc, δ123 # exactly like any other alpha character. (737, 456)
