有关此标志的文档/信息 [英] Documentation/Info on this sign
问题描述
有人能指出我使用的这个（和类似的）标志的文件在Python中使用
：
+ =
用法是：
x = + = len（y）
从字面上看，这是'变量x等于
''时髦符号 - 我想要学习'变量y的长度'
谢谢你，
巴特
Could someone point me to documentation on this (and similar) signs used
in Python:
+=
Usage would be:
x = += len(y)
Literally, that''s "variable x equals
''funky-symbol-that-I-want-to-learn-about'' the length of variable y"
Thank you,
Bart

这是什么意思？ 用法将是......？

What do you mean by this? "Usage would be"... ?

''funky-symbol-that-I-want-to-learn-about'' the length of variable y"
嗯？这没有意义......两个=和+ =是分配
语句，所以你不能把它们放在另一个之后。
你想做什么？

Huh? This doesn''t have meaning... both = and += are assignment
statements, so you can''t put one right after the other.
What are you trying to do?
