To use the if-else in one line in Python, we can use the expression: a if condition else b. In this expression, a is evaluated if the condition is True. If the condition is false, then b is evaluated. Let us use this as an example. Syntax of if else in one line 1 2 3 4...
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句,并且没有用分号分隔它们,但你的环境或工具错误地报告了这个错误。这通常不应该发生,因为 Python 通常会忽略没有分号的多个语句,...
