在这里,我们将使用外部 for 循环迭代列表。 外层for循环每次迭代,内层for循环执行5次,打印当前名称5次。 names = ['Kelly', 'Jessa', 'Emma'] # outer loop for name in names: # inner while loop count = 0 while count < 5: print(name, end=' ') #
if self.counter >= 10: raise StopAsyncIteration # increment the counter self.counter += 1 # simulate work await asyncio.sleep(1) # return the counter value return self.counter # main coroutine async def main(): # loop over async iterator with async for loop async for item in AsyncIterat...
def counter(): count = 0 def increment(): nonlocal count count += 1 return count return increment counter_func = counter() print(counter_func()) # 输出: 1 print(counter_func()) # 输出: 22.1.2 递归与匿名函数(lambda表达式) 递归是函数直接或间接地调用自身的过程,常用于处理分治问题。例如,...
除了for循环,我们还可以使用while循环来获取循环到第几次。 count=0whilecount<10:count+=1print(f'当前是第{count}次循环') 1. 2. 3. 4. 在上面的示例中,我们使用while循环来达到相同的效果,同样使用计数器变量来记录循环的次数。 类图 LoopCounter+ count: int+__init__()+increment() 在上面的类图中...

for i in range(5): print(i) This loop will print a sequence of numbers from 0 to 4, iterating a set number of times. Notice how the range function will automatically increment the i counter. The loop iterates through all values of i from 0 to 4, which correspond to a range of ...

We’ll output the numbers 0 to 9 in JavaScript with a for loop. To do this, we’ll define an integer variable called “number” and increment it if its value is less than 10. The code for this in JavaScript will probably look incomprehensible to beginners: for ( let number = 0; ...
