【python】python 一行 if else 語法 (one line if else) sample code (內含範例程式碼) 前言這個算是比較fancy的功能,有時為了排版漂亮、或邏輯已經很簡單,不需要撰寫多行程式碼時,才會使用。Sample Code 使用方法
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...

而且这些表达式可以包含运算符和函数调用。 line =f'In{round(num_years *12)}months I have spotted{num_camels}camels'line 'In 18 months I have spotted 23 camels' 所以我们可以像这样将数据写入文本文件。 writer =open('camel-spotting-book.txt','w') writer.write(f'Years of observation:{num_yea...

If you like one-liners, you’ll LOVE the book. It’ll teach you everything there is to know about asingle line of Python code.But it’s also anintroduction to computer science, data science, machine learning, and algorithms.The universe in a single line of Python!
Python If Else Statement The Python if else statement allows a program to choose between one of two code paths. It adds an else code block that only runs when the conditional is False. In an if else statement, either the if code block or the else code block are executed, but not both...

It’s a trivial edit to have the function return multiple values (in one set) as opposed to a boolean. All we need to do is drop the call tobool: We can further reduce the last two lines of code in the above version of our function to one line by removing the unnecessary use of...
