我有一些变数:
A1 = 'abc'
B1 = 'def'
C1 = 'ghi'
我想编写以下列格式打印A1,B1,C1的代码:
a+b+c, d+e+f, g+h+i
因此,在每个字符串值中,字符由+
分隔,字符串本身由,
分隔。
如何实现这一目标?

In [11]: str.join?
Namespace: Python builtin
Docstring:
S.join(iterable) -> string
Return a string which is the concatenation of the strings in the
iterable. The separator between elements is S.
In [12]: ", ".join("+".join(chars) for chars in [A1, B1, C1])
Out[12]: 'a+b+c, d+e+f, g+h+i'
