如果return在for循环的嵌套函数中,那么只有那个嵌套函数会被结束,外部的for循环和函数(如果有的话)将继续执行。 4. 给出示例代码,展示for循环中return的行为 python def test_return_in_for_loop(): for i in range(5): if i == 2: return "Found 2" print(f"Checking {i}") print("This line will...
可以通过调用生成器函数的next()方法来获取下一个返回的值。 defloop_generator():foriinrange(10):yieldi generator=loop_generator()forvalueingenerator:ifvalue==5:print(value)breakprint(value) 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 在上述示例中,生成器函数loop_generator()会在每次迭代时返回一...

The key word "return" which should be used only in a function inPythonprogramming language.If you use it in a "for" loop or else,an error like "SyntaxError: 'return' outside function" is supposed to appears . 如果你在方法外用了return 就会提示“ SyntaxError: 'return' outside function ”...
1、forloop方法: defodd_numbers(n):forxinrange(n):if(x % 2) == 1:yieldx num= odd_numbers(10)foriinnum:print(i) 2、next()方法: defodd_numbers(n):forxinrange(n):if(x % 2) == 1:yieldx num= odd_numbers(10)print(next(num))print(next(num))print(next(num))print(next(nu...
使用return退出循环是一种常见的编程技巧,它可以在函数中提前结束循环并返回一个值。在Python中,可以使用return语句来实现这一功能。 例如,以下代码将使用return退出循环: 代码语言:python 代码运行次数:0 复制 deffind_first_even_number(numbers):fornumberinnumbers:ifnumber%2==0:returnnumberreturnNone ...

def loop3(): for a in range(0,10): print a if a == 3: # We found a three, let's stop looping break print "Found 3!" loop3() 输出: 0 1 2 3 Found 3! 使用return 下面是一个示例,说明如何使用return在函数基于传入参数计算值之后返回值: ...
For an in-depth resource on this topic, check out Defining Your Own Python Function. To use a function, you need to call it. A function call consists of the function’s name followed by the function’s arguments in parentheses: Python function_name(arg1, arg2, ..., argN) You’ll...
