Example: Python if…else Statement number = int(input('Enter a number: '))ifnumber >0:print('Positive number')else:print('Not a positive number')print('This statement always executes') Run Code Sample Output 1 Enter a number: 10 Positive number This statement always executes If user enter...
elif boolean_expression_3: statement(s) else statement(s) 根据需要,有多少个 elif 并没有限制。 # Example Python elif k = 3 l = 6 ifk < l: print(k,'is less than', l) elifk > l: print(k,'is greater than', l) else: print(k,'equals', l) 执行和输出: 5. if 多条件表达式 ...

elif … sequence is a substitute for the switch or case statements found in other languages.可以有多个elif语句，关键词elif是else if的缩简写，用于缩减语句长度。if … elif … elif … 与其他语言的switch或case语句的作用相近。if condition_1:statement_block_1 elif condition_2:statement_block_2 else...
Example: x = 5 if x > 3: print("x is greater than 3") if .. else statement 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 : ...

if、elif和else if是最广为人知的控制流语句。它检查一个条件,如果为True,就执行后面的语句: if x < 0: print('It's negative') if后面可以跟一个或多个elif,所有条件都是False时,还可以添加一个else: if x < 0: print('It's negative') elif x == 0: print('Equal to zero') elif 0 < ...
It’s not clear that this has any significant advantage over the corresponding if/elif/else statement, but it is syntactically correct Python. Remove ads The Python pass Statement Occasionally, you may find that you want to write what is called a code stub: a placeholder for where you will ...
