Python Nested if Statements It is possible to include anifstatement inside anotherifstatement. For example, number =5# outer if statementifnumber >=0:# inner if statementifnumber ==0:print('Number is 0')# inner else statementelse:print('Number is positive')# outer else statementelse:print(...
Thenotkeyword is a logical operator, and is used to reverse the result of the conditional statement: Example Test ifais NOT greater thanb: a =33 b =200 ifnot a > b: print("a is NOT greater than b") Try it Yourself » Nested If ...
To perform more complex checks, if statements can be nested, one inside the other. This means that the inner if statement is the statement part of the outer one. This is one way to see whether multiple conditions are satisfied. For example: num = 12 if num > 5: print("Bigger than 5...
条件语句 (conditional statement) :在不同条件下完成不同动作 迭代循环 (iterative loop):重复的完成某些动作 3.1 条件语句 条件语句大体有四种格式: if 语句 if-else 语句 if-elif-else 语句 nested 语句 x = 1 1. # 给定二元条件,满足做事,不满足不做事。 if x > 0: print( 'x is positive' ) 1....
Also, don't be afraid to refactor a nested if statement into a multi-part boolean conditional. For example: # badifresponse:ifresponse.get("data"):returnlen(response["data"]) is better written as: # goodifresponseandresponse.get("data"):returnlen(response["data"]) ...
Python nested for loops and for loops and if statements combined. They are not necessarily considered to be Python basics; this is more like a transition to the intermediate level. Using them requires a solid understanding of Python3’s logic – and a lot of practicing, too. ...
_exit__ 返回 True，则异常被忽略；如果返回 False，则重新抛出异常 # 由外层代码对异常进行处理 if not exit(context_manager, *sys.exc_info()): raise finally: # 正常退出，或者通过 statement-body 中的 break/continue/return 语句退出 # 或者忽略异常退出 if exc: exit(context_...
Below is an example of two nested if-statements in Visual Basic and Python for comparison. Tab characters are used because the resulting code looks neater and more readable. Visual Basic: DimcountAsIntegerDimactiveAsBooleancount=1active=FalseIfcount>0ThenIfactiveThenMsgBox"Hello"EndIfEndIf ...
# nested loop # to iterate from 1 to 10 for j in range(1, 11): # print multiplication print(i * j, end=' ') print() 1. 2. 3. 4. 5. 6. 7. 8. 输出: 在这个程序中,外部 for 循环是从 1 到 10 迭代数字。 range() 返回 10 个数字。 所以外循环的总迭代次数是 10。
