实际上,你可以使用分号来分隔它们,但这并不常见,也不推荐,因为 Python 的代码风格(PEP 8)鼓励一行只写一个语句以提高可读性。 但是,如果你确实遇到了SyntaxError: multiple statements on one line (and no semicolon to separate them)这个错误,那通常意味着你可能有以下几种情况之一: 在一行中写了多个独立的语...
PEP 8: multiple statements on one line (colon) 解决方法:多行语句写到一行了,比如:if x == 2: print('OK')要分成两行写 PEP 8: line too long (82 > 79 characters) 解决方法:超过了每行的最大长度限制79 PEP 8: Simplify chained comparison 可简化连锁比较(例如:if a >= 0 and a <= 9: ...

SyntaxError: multiple statements found while compiling a single statement 这是因为整体复制过去运行而产生的错误;解决方案如下: 方法一:先将第一行复制,敲一下回车,再将剩下的部分复制过去,运行; 方法二:Ctrl+N,新建一个,这时直接将代码复制进来,就不会产生这个问题了;直接在IDLE中编译,是每行都要回车的。如...
foo = long_function_name(var_one, var_two, var_three, var_four) # 在缩进中添加4个空格(额外的缩进级别),以区分参数和其他部分 def long_function_name( var_one, var_two, var_three, var_four): print(var_one) # 悬挂缩进应该增加一个级别 ...

And then when I run the random choice, Python returns one of these numbers back to me. 如果我重复同一行,我会得到一个不同的答案,因为Python只是随机选取其中一个对象。 If I repeat the same line, I’m going to get a different answer,because, again, Python is just picking one of those obj...
Well, it did, but this particular import statement combines two different types of imports into one line: a relative import of the constants module within the library, and an absolute import of the sys module that is pre-installed in the Python standard library. In Python 2, you could ...
Often it is the case that even if you need to create a new object type,it is likely that this new object type resembles,in some way, an existing one. 通常情况下,即使需要创建新的对象类型,该新对象类型也可能在某种程度上类似于现有对象类型。 This brings us to inheritance, which is a fundam...
