跟着今天的课程,让我们在之前的"Week_03"文件中最下面增加一个单元格并标注“Elif Statements”. 运行原理 在前面的课程我们学到,条件语句赋予我们在程序中做决策的能力,接下来学习如何进行多项决策。在Python中,我们使用 Elif 语句基于提供的条件做另一项决策。elif 语句必须结合 if 语句使用,意味着你不能脱离 if...

statements(s) 1. 2. 例子:遍历一个字符串的每个字符。 str1="Hello"fori in str1:print(i) 1. 2. 3. 结果为:H e l l o 2,range()函数,生成一个整数数列,前开后闭,即后边的数字不能被打印。 如: fori inrange(1,3): 1. print(i) ...
In Python, the if..else statement has two blocks: one for when the condition is True and another for when the condition is False. Syntax: if expression : statement_1 statement_2 ... else : statement_3 statement_4 ... If the expression is True, the statements after if are executed...
Python also supports nested conditional logic, meaning that you can nestif,elif, andelsestatements to create even more complex programs. To nest conditions, indent the inner conditions, and everything at the same level of indentation will be run in the same code block: ...
Python中的IF/ELIF/ELSE语句 我才刚开始学习python,就困在elif语句上了。我在这里和网上都看到了如何准确地使用它们,我似乎使用了正确的语法等等,但当我运行它时,它给了我第一个elif语句的语法错误。请参阅下面的代码: height = float(input("enter your height in m: "))...
