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: ...

are two statements in a single line. This explains why the identities are different in a = "wtf!"; b = "wtf!", and also explain why they are same when invoked in some_file.py The abrupt change in the output of the fourth snippet is due to a peephole optimization technique known as...
Here are two examples of Python statements: # a single-line statement """ This is a multi-line comment. """ class Node: """ Create a Node and print it. """ def __init__(self,data): self.data = data self.next = next def __repr__(self): return "<Node data is: %s>" %...
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...
例如,long,multiple with-statements不能使用隐式继承,所以反斜杠是可以接受的: 换行符应在二元运算符之前还是之后? 几十年来,都是推崇在二元运算符之后换行的风格。但这可能会在两个方面损害程序的可读性:程序员不得不将视线分散到屏幕上的不同的行,并且程序员还需要把视线从找到的操作数上移到上一行上。 如此...
One line if else statement: a =2 b =330 print("A")ifa > belseprint("B") Try it Yourself » This technique is known asTernary Operators, orConditional Expressions. You can also have multiple else statements on the same line:
total = line_one + \ line_two + \ line_three #不需要缩进 在[], {}, 或 () 中的多行语句,不需要使用反斜杠(\),例如: total = ['item_one', 'item_two', 'item_three','item_four', 'item_five'] 7:Python基本数据类型 什么是数据类型?
