Conditional statements help users to implement their logic and handle conditions in their program. Any programming language supports conditional statements likeif, if-else, if-elif-else, etc. In Python, users can use theif notstatement apart from these conditional statements. This article will discus...

Python 中的 for 语句可以在任意序列上进行迭代访问,例如列表、字符串和元组。 B. 在Python 中 if…elif…elif… 结构中必须包含 else 子句。 C. 在Python 中没有 switch-case 的关键词,可以用 if…elif…elif… 来等价表达。 D. 循环可以嵌套使用,例如一个 for 语句中有另一个 for 语句,一个 while ...
elif x &> 5: print("x is more than 5") else: print("x is exactly 5") The Python IDE will shout with the error message: Syntax Error 3: Returning Python Statements Rather Than Expressions In all programming languages, the return keyword is used inside functions to return or save the ...
You might occasionally want to combine test expressions to evaluate multiple conditions in oneif,elif, orelsestatement. In this case, you'd use the Boolean operatorsandandor. Theoroperator You can connect two Boolean, or test, expressions by using the Booleanoroperator. For the entire expre...
If you want to check multiple conditions in sequence, you can use multiple if, elif (else if), and else statements. In this way, we can make more complex decisions. Example: Using chained if-elif-else Code: x=-20ifx>0:print("x is positive.")elifx==0:print("x is zero.")else:...
