减少嵌套:避免了深层嵌套的if-else结构,使得代码更加扁平化。 易于维护:当需要修改条件或者添加新的条件时,可以很容易地在函数开头添加新的检查。 避免冗余:去掉了不必要的else语句,因为每个if语句都有明确的返回点。 通过这种方式,提前返回使得代码更加简洁、直观,并且易于理解和维护。 使用合适的逻辑运算符 在Pyt
python if else语句例子 1. 嘿，你看如果你的分数大于 90 分，那就是优秀呀，就像你考试考得特别好，那肯定得夸夸你呀！比如：score = 95; if score > 90: print("优秀") else: print("还需努力")。2. 想想看呀，如果今天下雨，那你就得带伞，这不是很明显嘛！就好比：weather = "下雨"; if ...
When dealing with multiple conditions that need to be evaluated, Python’sif-elif-elsestructure is particularly useful. Theelifclause (short for “else if”) allows you to specify additional conditions to check if the initialifcondition is not met. This enables a more structured and efficient way...
In the above syntax expression1 is checked first, if it evaluates to true then the program control goes to next if - else part otherwise it goes to the last else statement and executes statement_7, statement_8 etc.. Within the if - else if expression2 evaluates true then statement_3, s...
Python if...else StatementIn computer programming, the if statement is a conditional statement. It is used to execute a block of code only when a specific condition is met. For example, Suppose we need to assign different grades to students based on their scores....
if expression: expr_true_suite else: expr_false_suite 避免“悬挂 else” /* dangling-else in C */ if (balance > 0.00) if (((balance - amt) > min_bal) && (atm_cashout() == 1)) printf("Here's your cash; please take all bills.\n"); ...
可以看出,if嵌套如何匹配else的,第一层if使用一个tab对齐,第二层使用一个空格对齐,切记elif 循环结构 while/for for 适用于list和dictionary的遍历,也可以是字符串遍历 word ="Programming is fun!"forletterinword:#Only print out the letter iifletter =="i":printletter ...
# 一行搞定if-else语句 # 案例一:if-else print("Yes") if 8 > 9 else print("No") # 输出:No # 案例二:if-elif-else E = 2 print("High") if E == 5 else print("数据STUDIO") if E == 2 else print("Low") # 输出:Low # 案例三:if if 3 > 2: print("Exactly") # 输出:Exa...

当在if 语句中运行条件时,Python 返回 True 或 False a = 200 b = 33 if b > a: print("b is greater than a") else: print("b is not greater than a") bool() 函数可让您评估任何值,并为您返回 True 或 False print(bool("Hello")) ...
